Abstract

Abstract: A high resistance ferromagnetic oxide Fe2⋅5Mn0⋅5O4 (FMO) property as a novel spin injector was investigated with a structure of a magnetic tunneling junction (MTJ) composed of FMO/Al–O/Ni80Fe20, in order to reduce an impedance mismatch problem on molecular spintronics. A tunneling magnetoresistance (TMR) effect in the MTJs was observed. The maximum TMR ratio observed in the MTJs was approximately 0.85% at room temperature (RT), and the spin-polarization of FMO was estimated to be at least 0.94% at RT. [Copyright &y& Elsevier]
