Abstract
The magnetization reversal process in the Fe/FeOxide granular systemconsisting of Fe nanoparticles embedded in a poorly crystallized oxide matrixhas been investigated at 5dKTd250K 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.File in questo prodotto:
