Effect of Element Doping and Substitution on the Electronic Structure and Macroscopic Magnetic Properties of SmFe-based Compounds
Takuya Yoshioka, Hiroki Tsuchiura, Pavel Novák
The mechanisms underlying the enhancement of magnetic anisotropies (MAs) of Sm ions, owing to valence electrons at the Sm site and the screened nuclear charges of ligands, are clar…
Finite-temperature magnetic properties of Sm2Fe17Nx using an ab-initio effective spin model
Shogo Yamashita, Daiki Suzuki, Takuya Yoshioka +2
In this study, we investigate the finite-temperature magnetic properties of Sm2Fe17Nx (x = 0,3) using an effective spin model constructed based on the information obtained by first…
Statistical and Analytical Approaches to Finite Temperature Magnetic Properties of SmFe
Takuya Yoshioka, Hiroki Tsuchiura, Pavel Novák
To investigate the magnetic properties of SmFe, we construct an effective spin model, where magnetic moments, crystal field (CF) parameters, and exchange fields at 0 K are d…
Magnetic properties in the metallic magnets with large anisotropy
Y. Taguchi, J. Nasu, A. Koga +2
We study low temperature properties in the metallic magnets, considering the itinerant electron mediated ferromagnetism. Applying the Monte Carlo simulations to the extended double…
Exciton-Mott Physics in Two-Dimensional Electron-Hole Systems: Phase Diagram and Single-Particle Spectra
Kenichi Asano, Takuya Yoshioka
Exciton Mott physics in two-dimensional electron-hole (e-h) systems is studied in the quasiequilibrium, which is the crossovers or phase transitions between the insulating exciton…
Quantum Phase Transitions in the Hubbard Model on Triangular Lattice
Takuya Yoshioka, Akihisa Koga, Norio Kawakami
We investigate the quantum phase transitions in the half-filled Hubbard model on the triangular lattice by means of the path-integral renormalization group (PIRG) method with a new…
