Impact of Lattice Distortions on Magnetocrystalline Anisotropy and Magnetization in (NdPr)FeB Alloys
Haruki Okumura, Takashi Miyake, Taro Fukazawa +6
NdFeB -- a widely used permanent magnet -- has magnetocrystalline anisotropy constants that differ between the bulk and interface regions. This study explores the effe…

Efficient method for magnetic structure exploration based on first-principles calculations: application to MnO and hexagonal ferrites SrFeO
Taro Fukazawa, Haruki Okumura, Tetsuya Fukushima +2
We propose an approach for exploring magnetic structures by using Liechtenstein's method for exchange couplings from the results of first-principles calculations. Our method enable…

Spin wave dispersion of 3d ferromagnets based on QSGW calculations
Haruki Okumura, Kazunori Sato, Takao Kotani
We calculate transverse spin susceptibility in the linear response method based on the ground states determined in the quasi-particle self-consistent (QSGW) method. Then we ex…
