Abstract

Hybrid magnetic nanostructures prepared from ultrathin ⁵⁷Fe layers alternating with thick Cr layers were studied by using polarized neutron reflectometry. It was shown that the sample with Fe layer thickness t = 2Å remains in superparamagnetic state at room temperature. Increasing the Fe-thickness to t = 4Å leads to crossover between superparamagnetic and ferromagnetic spin-glass Fe states and non-zero mean magnetic moment in Fe layers appears.
