摘要
Magnetoelectric switching of perpendicular exchange bias is observed in a Co/Pt multilayer attached to single crystalline magnetoelectric antiferromagnetic Cr2O3(111). The exchange bias field H-EB can be set to positive or negative values by applying an electric field E-fr either parallel or antiparallel to the magnetic freezing field H-fr while cooling to below the Neel temperature. Based on this result, the antiferromagnetic spin state can be used as a medium for data storage. The authors propose magnetic random access memory cells and magnetic logic devices, which are purely voltage controlled. (c) 2006 American Institute of Physics.
