The dynamical behavior of g-Fe 2 O 3 particles dispersed in a polymer have been investigated by a.c. susceptibility and Mo ¨ssbauer spectroscopy measurements. The effect of interparticle interactions on the relaxation time is satisfactorily described by a superparamagnetic model where the dipolar en
