Abstract

Fe/Cr multilayers with composite layered structures were prepared onto MgO (100) and glass substrates by alternate deposition in ultrahigh vacuum. A multilayer with two thicknesses of Fe layers shows a larger MR change, 6.2 % at RT and 13.5 % at 77 K, than a simple type ones with the applied field upto 3 k0e. This Is due to the ferrimagnetically coupled Fe layers. For the multilayers of Cr-composite type, the MR ratio could be enhanced, 12.9 % at RT with the field of 2 T.
