The tunnel magnetoresistance (TMR) is one of the most important spintronic phenomena but its reduction at finite temperature is a severe ...

スピネルバリアを用いた磁気トンネル接合Fe/MgAl2O4/Feの電圧特性を理論的に解析し、その結果をFe/MgO/Feの電圧特性と比較した。その結果、Fe/MgAl2O4/Feでは電極でのバンド折りたたみが起こるため、磁気抵抗比の電圧耐性がFe/MgO/Feよりも高くなる...

We study theoretically the anisotropic magneto-Peltier effect, which was recently demonstrated experimen-tally. A first-principles-based ...

We study interfacial magnetocrystalline anisotropies in various Fe/semiconductor heterostructures by means of first-principles calculatio...

We theoretically study the tunnel magnetoresistance (TMR) effect in (111)-oriented junctions Co/MgO/Co(111) and Ni/MgO/Ni(111). The Co-ba...
