摘要
Spin-transfer driven switching was observed in MgO based magnetic tunnelling junctions (MTJ) with tunnelling magneto resistance ratio of up to 160% and the average intrinsic switching current density (J(c0)) down to 2 MA/cm(2), which are the best known results reported in spin-transfer switched MTJ nanostructures. Based on a comparison of results both from MgO and AlOx MTJs, further switching current decrease via MgO dual structures with two pinned layers is discussed. (C) 2006 Elsevier B.V.
