title: Searching for evidence of gapped quantum spin liquid state in a Shastry-Sutherland magnet Yb2Be2GeO7

description: Gapped or gapless is important to distinguish between different types of quantum spin liquids. While a gap is vital for the quantum computations, its presence in the quantum spin liquid candidates is relatively rare. Here, we show the possible existence of a small gap in a Shastry-Sutherland magnet, which may also possess a quantum spin liquid disordered state. In order to detect the small gap, as well as an excitation continuum, we propose to perform inelastic neutron scattering measurements on the LET spectrometer equipped with a dilution refrigeration and 9 T magnet.

title: Long-periodicity magnetic spirals and possible field-induced magnetic skyrmions in topological kagome metals Er1-xTbxMn6Sn6

description: It has recently been realised that TbMn6Sn6 and the related magnetic kagome metals stand out as a unique quantum material system that boasts emergent topologically non-trivial states in both k-space and real space. Understanding and eventual manipulation of these exotic quantum states can lead to potential technological applications in spintronics and quantum technologies. However, the identification of long-periodicity magnetic spirals and the field-induced magnetic skyrmions in TbMn6Sn6 have not been achieved with neutron diffraction. We therefore propose to carry out a comprehensive SANS study on both TbMn6Sn6 and the related Er0.75Tb0.25Mn6Sn6 single crystals at ZOOM or SANS2D. 5 days of measurement time are necessary.

title: Translational Dynamics in the Solvated Electron-Alkalide Analogues Li-MeNH2 and LiNa-MeNH2

description: This proposal aims to determine the differences in methylamine dynamics in metallic, electroytic, and alkalidic solutions. The large differences in density and the visual behaviour of the liquids suggests very different motional dynamics which will be determined from QENS measurements at various temperatures. Furthermore, elastic fixed window scans will be taken for the samples across their solid and liquid phases to identify points of dynamic transitions which can be correlated with structural phases that are currently under investigation.

title: The Magnon Excitation Energy Scale in TbRu2Si2

description: Magnons are the excitations associated with long range magnetic order. TbRu2Si2 develops multi-Q magnetic order below 56K. In our recent crystal field experiment on Mari we did not observe signatures of the magnon excitations. One possible explanation for this is that the spin excitations are steep in energy and exist at lower-Q (outside of the Mari coverage). Longer single-run counting times may also be required (&gt;4 hrs) since the spectral intensity will be spread over many different bands. This would make MAPS a better instrument for detecting these excitations, so that the energy scale of the magnetic excitations may be ascertained. Using various Ei's, we intend to search for these magnon excitations at low-Q so that their energy scale can be determined as a feasibility study for future single-crystal INS investigations on this system.

title: Investigating the Structure of Liquid Benzene:Acetonitrile Mixture

description: Benzene and acetonitrile are two of the most commonly used solvents in most chemistry laboratories and are found as a mixture in various different environments. To date, there is only one study of this mixture's structure as a co-crystal. Therefore, this proposal aims to use SANDALS to fully characterise the structure of the 3:1 benzene:acetonitrile mixture as a liquid for the first time to expand on the incredibly limited literature. This will be done by employing standard isotopic substitution and taking advantage of SANDALS’ high resolution operating Q range that will give us great insight into the molecular and bulk structure of the mixture. For this, we request 2 days of beam time with the sample changer.

title: Investigation of the structural and magnetic clustering near the PV-BM topotactic phase transition in LSMO films by PNR

description: Controlled oxygen release/uptake in complex oxides can induce changes of the crystal structure and simultaneously of the magnetic and electrical properties. In La1-xSrxMnO3 (LSMO) the gradual oxygen desorption triggers a phase transition from the initial ferromagnetic (FM) perovskite (PV) structure to an oxygen vacancy layered antiferromagnetic (AFM) brownmillerite (BM) structure, i.e. La1-xSrxMnO2.5. Our previous work suggests a potential structural and magnetic clustering process during this phase transition. We propose to measure half-polarized PNR at POLREF to gain additional information on the potential clustering phenomena compared with GISANS. This study aims for a systematic and comprehensive understanding of the oxygen vacancy induced topotactic phase transition on two length scales (i.e., microscopic and mesoscopic), revealing the relationship between the presence of oxygen vacancies and the resulting structural and magnetic evolution. Such an understanding is important for the design of novel ionotronic devices.

title: Neutron diffraction measurements of residual stress in additive and subtractive hybrid manufactured (CoCrNi)94Ti3Al3 medium entropy alloy

description: (CoCrNi)94Ti3Al3 medium entropy alloy (MEA) exhibits excellent properties that are superior to traditional
 alloys and possess the potential for service under specific working conditions. However, high-technology
 developments have required the integrated complicated components (e.g. sharp corners, thin-walled
 structures and curved shapes) with high-quality surface roughness, and dimensional accuracy. With this in
 mind, additive and subtractive hybrid manufacturing (ASHM), in which additive manufacturing (AM) can
 generate raw parts with near-net-shape dimensional characteristics whereas subtractive machining (SM)
 operations achieve the desired dimensional accuracy and surface finish, maybe a superior manufacturing
 strategy of utilizing high-performance MEA parts. It is particularly noteworthy that the SM process
 complicates the residual stress generated by the thermal history of the AM process. The complex stress
 distribution may cause component warping and cracking, deteriorating the service performance. We
 therefore propose to study the distribution and evolution of the residual stress in the ASHM-fabricated
 MEAs, to lay a reliable theoretical foundation for manufacturing high performance components.

title: Magnetic excitations in quasi-one-dimensional zigzag chain antiferromagnet: SrCoV2O7

description: Structural analysis from the x-ray diffraction data for SrCoV2O7 has been confirmed the zigzag arrangement of Co2+ ions in a quasi-one-dimensional chain. Magnetic susceptibility and heat capacity measurements revealed an antiferromagnetic phase transition at Neel temperature (TN) ∼ 3.5 K, characterized by a decrease in susceptibility below TN, and negative Curie-Weiss temperatures. Here, we proposed to investigate CEF excitations at various temperature and energies. The results of the proposed study will provide the direct microscopic evidence of the nature of spin state from the Co2+ zigzag chain antiferromagnet of the SrCoV2O7. The acquired knowledge from the present study will be helpful to understand the magnetic excitations along with spin sate and CEF energy level splitting. excitations present in the antiferromagnetic Co2+ CaCoV2O7. The Co2+ ions is in the distorted octahedral environment and are expected to have an effective spin-1/2 due to spin-orbit coupled Kramers doublet ground state, very much similar to the CaCoV2O7 [Ref. Isha et al. PRR 6, L032010 (2024)]. This could be confirmed by measuring the crystal field excitations using an inelastic neutron scattering study at MERLIN beamline.

title: LF musr study of magnetic phases and spin dynamics in a Shastry-Sutherland Quantum Magnet

description: In 2D magnetic compounds, the Shastry-Sutherland lattice (SSL) – a square lattice with an antiferromagnetic exchange J between dimerized nearest neighbours and J’ between next-nearest-neighbours, has attracted attention due to its complex phase diagram, displaying a variety of novel phases as function of magnetic field. The 2D SSL model, consisting of an orthogonal dimer network of spin S=1/2, represents one of the very few topologies where the ground state of a geometrical frustrated lattice could be exactly solved. Previous experimental realizations of the SSL model such as SrCu2(BO3)2 (SCBO) exhibit multiple magnetization plateaus at fractional values, but the critical fields have previously been much too large for muSR studies. Lately, a new rare-earth SSL compound Er2Be2GeO7 with weaker interactions that SCBO was found to show magnetization plateaus with critical fields below 1T, giving the first opportunity for muSR to provide a local probe study of the magnetic properties of the SSL lattice.
