title: Data for Paper "Critical phenomenon of the layered chiral helimagnetic YbNi3Al9"

description: Single-crystals of YbNi3Al9were grown by the self-flux technique method using excessive Al as a flux. Powders of Yb (purity 3N), Ni (4N), and Al (5N)with a ratio of Yb: Ni: Al = 1: 3: 20 were sealed in a vacuumed quartz tube, and heated to 1173 K. After hold for 12 h, the temperature was cooled to 973 K at a rate of 2 K h−1 . The excess flux was removed by centrifugation at 973 K. Finally, the sample was soaked in hydrochloric acid to exclude extra flux. The chemical compositions of the single crystal were carefully checked by energy dispersive x-ray (EDX)spectrometry. The crystal structure and orientation were determined by x-ray diffraction (XRD) using high-intensity graphite monochromatized Cu Kα radiation. The single crystals were ground into powder to gain the powder XRD pattern, which was refined by the Rietveld method. The magnetization was measured using a Quantum Design vibrating sample magnetometer(SQUID-VSM). To ensure precise field and magnetization, the data was collected after relaxing for 2 min with a no-overshoot mode. In particular, when measuring the initial isothermal magnetization, the sample was cooled to the target temperature under zero field after heated above TC adequately for 10 min.

description: Single-crystals of YbNi3Al9 were synthesized by the self-flux method. Powders of Yb (purity 3N), Ni (4N), and Al (5N) with a ratio of Yb: Ni: Al = 1: 3: 20 were sealed in a vacuumed quartz tube, where the extra Al was used as a flux. The mixed powder in the vacuumed tube was heated to 1173 K, and hold at that temperature for 12 h. Then, the temperature was cooled to 973 K at a rate of 2 K h−1 . The flux was removed by centrifugation at 973 K. Finally, the as-grown single crystals were soaked in hydrochloric acid to exclude extra flux. The chemical constituents of the single crystal were checked by energy dispersive x-ray (EDX) spectrometry, which are close to the desired proportions. The crystal structure and orientation were determined by x-ray diffraction (XRD). The magnetization was performed using a Quantum Design vibrating sample magnetometer (SQUID-VSM). The initial isothermal magnetization was carried out after the sample heated adequately above TC with a no-overshoot mode.

title: Data for Paper "Critical behavior of the magnetic Weyl semimetal PrAlGe"

description: Single crystals of PrAlGe were prepared by a self-flux technique using extra Al as a flux. The detailed growth process was described in a previous report. The crystal structure of PrAlGe was checked by the x-ray diffraction (XRD), performed on a Rigaku-TTR3 x-ray diffractometer, with high intensity graphite monochromatized Cu Kα radiation. The chemical compositions of the single crystal were checked by energy dispersive x-ray (EDX) spectrometry. The magnetization measurements, including the angle-, temperature-, and field-dependent magnetization, were carried out by a Quantum Design vibrating sample magnetometer (SQUID-VSM). In order to obtain the magnetic entropy change, the initial isothermal magnetization with field applied along the c axis (H//c) was measured. Before each measurement of initial isothermal magnetization, the sample was heated to room temperature and held for 2 min, then cooled to the target temperature under zero field. The magnetic field was relaxed before data collection, and a no-overshoot mode was applied to ensure a precise magnetic field. The magnetization under high magnetic field beyond 7 T was performed on the water-cooling resistive magnet.

title: Data for Paper "Tricritical phenomenon and H-T phase diagram in a single crystal of the double-perovskite iridate La2ZnIrO6"

description: Single crystals of La2ZnIrO6 were grown by the KF flux method. A polycrystalline sample of La2ZnIrO6 was first prepared by the solid state reaction using stoichiometric starting materials La2O3 (99.9%, Alfa Aesar) and IrO2 (99.9%). Then, single crystals were grown by combining the polycrystalline sample with KF flux in a ratio of 1 : 300. After being heated to 1100 ◦C and annealed for 5 h, the as-grown sample was slowly cooled down to 850 ◦C at a rate of 2 ◦C/h. The single crystals were obtained from the flux by dissolving the flux in water. The chemical compositions were carefully checked by the energy dispersive x-ray (EDX) spectrometry. The crystal structure and orientations were determined by the Rigaku Gemini S Ultra four-circle single crystal x-ray diffractometer (XRD). The magnetization was measured using a quantum design vibrating sample magnetometer (SQUID-VSM). The no-overshoot mode was applied to ensure a precise magnetic field. The magnetic field was relaxed for two minutes before data collection. For the measurement of initial isothermal magnetization, the sample was first heated adequately above the phase transition temperature for 10 min, then cooled to the target temperature under zero magnetic field.

description: Single-crystal Cr2Ge2Te6 was prepared by the self-flux technique using extra Ge and Te as a flux. The crystal structure of Cr2Ge2Te6 was checked by x-ray diffraction (XRD), which was performed on a Rigaku-TTR3 x-ray diffractometer with high intensity graphite monochromatized Cu Kα radiation. The magnetization measurements, including the angle-, temperature-, and field-dependent magnetizations, were carried out on a Quantum Design vibrating sample magnetometer (SQUID-VSM). In order to obtain the magnetic entropy change, the initial isothermal magnetization around the phase-transition temperature (TC) along the c axis was measured. The magnetic field was decreased to zero field in an oscillation mode to exclude the influence of the remaining field. Before each measurement of initial isothermal magnetization, the temperature was warmed adequately above TC held for 2 min and then cooled to the target temperature. The magnetic field was relaxed before data collection, and a no-overshoot mode was applied to ensure a precise magnetic field.

description: Polycrystalline samples of A2Ir2O7 (A ¼ Gd, Eu, and Sm) weresynthesized by the solid-state reaction method. The starting ma-terials, powders of A2O3 (purity 99.9%) and IrO2 (99.99%) weremixed thoroughly according to the stoichiometric ratio of 1: 2.1. Themixed powders were sintered at 1373 K for 4 days with severalintermediate grindings. After adding 10% IrO2, the powder sampleswere pressed into pellets. Then, the samples were sintered at1423 K for another 4 days. The structure and phase purity werechecked by the Rigaku-TTR3 X-ray diffractometer with high-intensity graphite monochromatized Cu Ka radiation. The re-sistivity measurements were performed using the conventionalfour-probe method with the temperature varied using a closed-cycle helium refrigeration unit. The hydrostatic high-pressure re-sistivity measurements were carried out using a clamp-type piston pressure cell and employed Daphne 7373 oil as the medium totransmit pressure with a high level of high homogeneity. To cali-brate the pressures at room temperature, we used Cu2O powder asa manometer, whose nuclear quadrupole resonance frequency as afunction of pressure has been determined very accurately.

description: Single-crystals of MnNb3S6 were grown by the chemical vapor transport (CVT) method. The powders of Mn, Nb, and S in high purity (99.9 %) were sealed in silica tube, which was heated to 800 ◦C. The two ends of the tube are kept at 800 ◦C and 950 ◦C respectively for several days. The I2 was used as the transport gas. The sample preparation method, chemical compositions, determination of crystal orientations were described in details elsewhere [1]. The magnetization was measured using a Quantum Design vibrating sample magnetometer (SQUID-VSM). The ESR spectra were carried out using a Bruker EMX plus model spectrometer operating at X-band frequencies (9.4 GHz). The applied magnetic field was rotated from the ab-plane to the c-axis. To ensure a precise magnetic field and data, the magnetic field was applied with no-overshoot mode, and relaxed for 2 minutes before data collection. The ESR spectra were collected at selected temperatures, where the variation of temperature was performed by a helium continuous flow thermostat.
