The dc susceptibility and magnetization relaxation were investigated on ferromagnetic particles dispersed in a polymer matrix with different configurations of particles in which a strong interparticle interaction is realized. The results suggest that intraparticle anisotropy is dominant in the relaxation process below 10 K, whereas the magnetic property is mainly influenced by interparticle interaction above 10 K.
