Abstract
The magnetization reversal process in the Fe/FeOxide granular system - consisting of Fe nanoparticles embedded in a poorly crystallized oxide matrix - has been investigated at 5 K ≤ T ≤ 250 K by the remanence curve technique. The analysis of the thermal and field dependence of the isothermal and demagnetized remanence curves confirms and supports the progressive freezing of the system towards a cluster-glass-like state. © 2003 Elsevier B.V.
