Electronic Origin of Phase Stability in Mg-Zn-Y Alloys with a Long-Period Stacking Order
Takao Tsumuraya, Hiroyoshi Momida, Tamio Oguchi
The origin of the phase stability of 18 Mg-Zn-Y alloys with a long-period stacking order (LPSO) is studied using first-principles calculations. We calculate the heat of formatio…
First-Principles Study on Cathode Properties of Li2MTiO4 and Na2MTiO4 (M = V, Cr, Mn, Fe, Co, Ni)
Kunihiko Yamauchi, Hiroyoshi Momida, Tamio Oguchi
The cathode properties of Na2MTiO4 (M: transition-metal element) are investigated by means of density-functional-theory calculations. The stability between the layered structure an…
Effect of magnetocrystalline anisotropy on magnetocaloric properties of AlFeB compound
Hung Ba Tran, Hiroyoshi Momida, Yu-ichiro Matsushita +4
It is well known that the temperature dependence of the effective magnetocrystalline anisotropy energy obeys the power law of magnetization in the Callen-Callen theory.…
Anisotropic magnetocaloric effect of CrI: A theoretical study
Hung Ba Tran, Hiroyoshi Momida, Yu-ichiro Matsushita +2
CrI is considered to be a promising candidate for spintronic devices and data storage. We derived the Heisenberg Hamiltonian for CrI from density functional calculation…
Computational study of the dielectric properties of [La,Sc]2O3 solid solutions
Hiroyoshi Momida, Eric Cockayne, Naoto Umezawa +1
First-principles calculations were used to compute the dielectric permittivities of hypothetical [La,Sc]2O3 solid solutions in the cubic (bixbyite) and hexagonal La2O3 phases. Diel…
