Anisotropic Exchange Spin Model to Investigate the Curie Temperature Dispersion of Finite-Size L10-FePt Magnetic Nanoparticles
Kohei Ochiai, Tomoyuki Tsuyama, Sumera Shimizu +5
We developed an anisotropic spin model that accounts for magnetic anisotropy and evaluated the Curie temperature (Tc) dispersion due to finite size effects in L10-FePt nanoparticle…

Driving force of atomic ordering in FePt, investigated by density functional theory and machine-learning interatomic potentials Monte Carlo simulations
Tomoyuki Tsuyama, Takeshi Kaneshita, Akira Matsui +8
We report the mechanisms of atomic ordering in FePt alloys using density functional theory (DFT) and machine-learning interatomic potential Monte Carlo (MLIP-MC) simu…
