Fermi surface and light quasi particles in hourglass nodal chain metal \b{eta}-ReO2
Daigorou Hirai, Takahito Anbai, Takako Konoike +8
Quantum oscillations in magnetic torque and electrical resistivity were measured to investigate the electronic structure of \b{eta}-ReO2, a candidate hourglass nodal chain metal (D…
Pseudogap Formation in the Nodal-Line Semimetal NaAlGe
Takahiro Yamada, Daigorou Hirai, Tamio Oguchi +2
NaAlSi and NaAlGe are isostructural and isoelectronic semimetals with topological nodal lines close to the Fermi level. Despite having virtually identical electronic structures, Na…
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…
