Abstract

Fe(x)/Ag(2.6 nm) multilayer heterostructures containing Fe layers of periodically altered thickness have been prepared by molecular beam evaporation to study the influence of ferromagnetic layers on the magnetic properties of granular multilayers. The magnetic properties were examined by SQUID magnetization measurements and Mössbauer spectroscopy, and the magnetoresistance was measured in parallel and transversal magnetic fields up to 12 T. Samples with x=0.2 and 1.5 nm were prepared both as separated and as interleaved multilayer heterostructures. The average blocking temperature of the granular Fe layers (x=0.2 nm) is not altered when the thickness of every fourth layer is increased to 1.5 nm. On the other hand the temperature dependence of the magnetoresistance was found to be significantly different for the separated and the interleaved samples.
