title: Fabrication and magnetotransport properties of ordered sub-100 nm pseudo-spin-valve element arrays.
abstract: We prepared ordered sub-100 nm pseudo-spin-valve (PSV) element arrays by electrodeposition of NiFe/Cu/Co into the pores of self-organized nanoporous anodized aluminium templates. Field-emission scanning electron microscopy reveals that the sub-100 nm PSV arrays, of uniform size, are well separated and exhibit a perfect two-dimensional array with a hexagonal pattern. The easy-axis hysteresis loops show two distinct steps related to the separate reversal of soft (NiFe) and hard (Co) layers. The switching fields of the PSV arrays are approximately -50 Oe for the NiFe and 570 Oe for the Co. The dependence of the magnetoresistance on the Cu spacer layer thickness indicates the presence of an oscillatory interlayer exchange coupling through the Cu layers.
