### Document Type Evaluation  
Figure 8 depicts the ranking of the most cited papers based on the number of publications provided by each journal and the impact factors. The selected 100 most-cited articles were published in 28 distinct journals that Scopus indexed. This demonstrates the diversity of publication distributions and widespread interest in YIG-related research. _Physical Review B_ was the most influential journal, comprising 28 (28%) publications out of all the journals. _Physical Review Letters_ and _Applied Physics Letters_, with 14 articles (14%), were the second-most-cited journals. The third most-cited journal is _Nature Communications_, with 5 articles (5%). The journals that had the fourth-highest number of papers (3%) were _Nano Letters_, _Journal of Applied Physics_, _Optic Express_, and _Physical Review Applied_. _Nature Physics_, _Journal of Materials Chemistry C_, _ACS Photonics_, _Journal of Magnetism and Magnetic Materials_, _Nanoscale_, _Optical Materials Express_, and _IEEE Magnetics Letters_ correspond to the fifth-ranked journal, each of which had two articles featured in the list (2%). _APL Materials_, _Nature Materials_, _Journal of Physics D_, _Advanced Electronic Materials_, _Optics Letters_, _Journal of the European Ceramic Society_, _Journal of Alloys and Compounds_, _AIP Advances_, _Ceramics International_, _Applied Physics Express_, _Applied Surface Science_, _Advanced Optical Materials_, and _Physica Status Solidi (B)_ were the sixth-ranked journals with one paper each (1%). The three most influential journals were _Physical Review B_, _Physical Review Letters_, and _Applied Physics Letters_, which had impact factors of 3.908, 9.185, and 3.971, respectively. The journal articles published in _Nature Materials_ had the highest impact factor, which was 47.66. There was  
only one paper published in _Nature Materials_ based on work done by [PERSON] et al. [76]. The paper [76] ranks 25 th, with contributions from 12 authors who published work in 2017. The paper presents a spin Nernst effect observation for the optimization of spintronics. The impact factors of all top citation papers ranged between 1.54 and 47.66. Figure 9 examines the journals according to the publisher and active areas in YIG research. In Figure 9, 11 distinct publishers were identified for the 100 most-cited papers. The American Physical Society (APS) published high-quality publications of 45% of the most cited papers. The related journals that were published in APS were _Physical Review B_, _Physical Review Letters_, and _Physical Review Applied_. The most frequently cited publication was _Physical Review B_ (28%), followed by _Physical Review Letters_ (14%) and _Physical Review Applied_ (3%). In addition, the first- [13] and second-ranked [36] top papers were published in _Physical Review Letters_, which were published by the APS. The impact factors of the associated papers were 9.185, which is rather high. The third- [18] and fourth-ranked [68] papers appeared in _Physical Review B_, which was published by the same publisher, APS, and had an impact factor of 3.908. The remaining publishers involved in the YIG publications were Applied Physics Letters (AIP) (19%), Elsevier (6%), Optica (6%), American Chemical Society (ACS) (5%), Nature Research (5%), Royal Society of Chemistry (RCS) (4%), Nature Publishing Group (3%), Wiley-VCH (3%), Institute of Electrical and Electronics Engineers (IEEE) (2%) and Institute of Physics (IOP) Publishing (2%). Figure 8: Evaluation of top citation papers over various journals and journal impact factors. It is acknowledged that Nature Publishing Group publishes one of the most widely-read, prestigious, and high-quality academic publications in the world. As seen in Figure 9, Nature Publishing Group has the highest impact factor compared with the other publishers. Intriguingly, three YIG publications have been published by the Nature Publishing Group in _Nature Materials_[76] and _Nature Physics_[10; 23].
