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 the specific heat jump in the glass transition of silica glass and the Prigogine-Defay ratio
Koun Shirai, Kota Watanabe, Hiroyoshi Momida
The most important characteristic of glass transition is a jump in specific heat . Despite its significance, no standard theory exists to describe it. In this study, first-…
First-principles study on the specific heat of glass at glass transition with a case study on glycerol
Koun Shirai, Kota Watanabe, Hiroyoshi Momida
The standard method to determine the transition temperature (Tg) of glass transition is the jump in the specific heat. Despite this importance, standard theory for this jump is lac…
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…
