Abstract

The structural, electrical, and magnetic properties of Fe₃O ₄/Au/Fe spin valves on MgO(001) are presented. In contrast to more conventional spin valve structures, the current-in-plane resistance of the Fe₃O₄/Au/Fe spin valves is found to be smallest for an antiparallel alignment of the magnetization of the Fe₃O₄ and Fe layer. Since the electrical current is transported through the low resistance Au and Fe layers, the negative magnetoresistance effect is attributed to an inverse electron spin scattering asymmetry at the Fe₃O ₄/Au interface.
