Abstract
Magnetic properties of Fe particles, with the size around 2 nm, in gra nular Fe-MgF2 films were investigated by DC and AC magnetization measu rements. Anomalous two cusps appeared in zero-field cooled magnetizati on and AC susceptibility against temperature. Large nonlinear suscepti bility suggests the freezing of moments induced by magnetic interactio n between particles.
