Here we present ab initio calculations of the tensorial exchange interactions of hematite and use them to understand its magnetic properties by parametrizing a semiclassical Heisenberg spin model. Using atomistic spin dynamics simulations, we calculate the equilibrium properties and phase transitions of hematite, most notably the Morin transition. The computed isotropic and Dzyaloshinskii-Moriya interactions result in a Neel temperature and weak ferromagnetic canting angle that are in good agreement with experimental measurements. Our simulations show how dipoledipole interactions act in a delicate balance with first and higher-order on-site anisotropies to determine the material's magnetic phase. Comparison with spin-Hall magnetoresistance measurements on a hematite single crystal reveals deviations of the critical behavior at low temperatures. Based on a mean-field model, we argue that these differences result from the quantum nature of the fluctuations that drive the phase transitions.}, keywords = {neutron-diffraction; WEAK FERROMAGNETISM; Materials Science, Multidisciplinary; Physics, Applied; BASAL-PLANE}, year = {2023}, eissn = {2469-9969}, orcid-numbers = {Deák, András/0000-0002-3210-2947; Rózsa, Levente/0000-0001-9456-5755} } @article{MTMT:33887288, title = {Search for large topological gaps in atomic spin chains on proximitized superconducting heavy-metal layers}, url = {https://m2.mtmt.hu/api/publication/33887288}, author = {Beck, P. and Nyári, Bendegúz Tamás and Schneider, L. and Rózsa, Levente and Lászlóffy, András and Palotás, Krisztián and Szunyogh, László and Ujfalussy, Balázs and Wiebe, J. and Wiesendanger, R.}, doi = {10.1038/s42005-023-01196-y}, journal-iso = {COMM PHYS}, journal = {COMMUNICATIONS PHYSICS}, volume = {6}, unique-id = {33887288}, issn = {2399-3650}, year = {2023}, eissn = {2399-3650}, orcid-numbers = {Nyári, Bendegúz Tamás/0000-0001-5524-9995; Rózsa, Levente/0000-0001-9456-5755; Palotás, Krisztián/0000-0002-1914-2901} } @article{MTMT:33728446, title = {Effects of strong spin-orbit coupling on Shiba states from magnetic adatoms using first-principles theory}, url = {https://m2.mtmt.hu/api/publication/33728446}, author = {Park, K. and Nyári, Bendegúz Tamás and Lászlóffy, András and Szunyogh, László and Ujfalussy, Balázs}, doi = {10.1088/1367-2630/acc1ff}, journal-iso = {NEW J PHYS}, journal = {NEW JOURNAL OF PHYSICS}, volume = {25}, unique-id = {33728446}, issn = {1367-2630}, year = {2023}, eissn = {1367-2630}, orcid-numbers = {Nyári, Bendegúz Tamás/0000-0001-5524-9995} }
