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…

Designing single and degenerate flat bands in the kagome lattice with long-range hopping
Yuta Taguchi, Motoaki Hirayama, Takashi Miyake
We investigate the electronic structure of the kagome lattice model with first, second, and two kinds of third nearest-neighbor hoppings. We reveal that by tuning the third nearest…
