NMR verification of Dirac nodal lines in a single-component molecular conductor
Takahiko Sekine, Keishi Sunami, Takumi Hatamura +6
The Dirac nodal line (DNL) is a novel form of massless Dirac fermions that reside along lines in momentum space. Here, we verify genuine DNLs in the molecular material, [Ni(dmdt)$_…
First-principles studies of spin-orbital physics in pyrochlore oxides
Hiroshi Shinaoka, Yukitoshi Motome, Takashi Miyake +2
The pyrochlore oxides O exhibit a complex interplay between geometrical frustration, electronic correlations, and spin-orbit coupling, due to the lattice structure and…
First-principles study on stability and magnetism of NdFe11M and NdFe11MN for M=Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn
Yosuke Harashima, Kiyoyuki Terakura, Hiori Kino +2
Recently synthesized NdFe12N has excellent magnetic properties, while it is thermodynamically unstable. Using first-principles method, we study the effect of substitutional 3d tran…
Nitrogen as the best interstitial dopant among =B, C, N, O and F for strong permanent magnet NdFeTi: First-principles study
Yosuke Harashima, Kiyoyuki Terakura, Hiori Kino +2
We study magnetic properties of NdFeTi, where =B, C, N, O, and F, by using the first-principles calculation based on the density functional theory. Its parent compound…
Weyl Node and Spin Texture in Trigonal Tellurium and Selenium
Motoaki Hirayama, Ryo Okugawa, Shoji Ishibashi +2
We study Weyl nodes in materials with broken inversion symmetry. We find based on first-principles calculations that trigonal Te and Se have multiple Weyl nodes near the Fermi leve…
Second-order Perturbation Formula for Magnetocrystalline Anisotropy using Orbital Angular Momentum Matrix
Taichi Kosugi, Takashi Miyake, Shoji Ishibashi
We derive a second-order perturbation formula for an electronic system subject to spin-orbit interactions (SOI). The energy correction originates in the spin-conserving and the spi…
