Unbiased first-principles construction of complete tensorial spin Hamiltonians
Haichang Lu, Boyang Deng, Hiroshi Katsumoto +3
Magnetic ground states are commonly predicted using spin Hamiltonians whose interaction terms are selected a priori, potentially overlooking the microscopic interactions that gover…
Two Microscopic Mechanisms of Piezomagnetism in CoF from First-Principles Calculations
Hiroshi Katsumoto, Tamio Oguchi, Kunihiko Yamauchi
Rutile-structured CoF has long been recognized as a prototypical piezomagnetic material. Recently, it has attracted renewed interest as an altermagnet, exhibiting spin-split el…
Linked skyrmions in shifted magnetic bilayer
Sumit Ghosh, Hiroshi Katsumoto, Gustav Bihlmayer +6
Magnetic solitons have recently attracted significant attention due to their intricate physical properties and potential applications in information processing. The majority of the…
First-principles Study on Piezoelectricity and Spontaneous Polarization in Bi(Fe,Co)O3
Hiroshi Katsumoto, Kunihiko Yamauchi, Tamio Oguchi
Solid solution BiFe1-xCoxO3 shows anti-ferromagnetic order and pyroelectric order, simultaneously. It has been known that BiFe1-xCoxO3 exhibits a structural phase transition betwee…
