T. Oku et al., MAGNETIC-PROPERTIES OF FERROMAGNETIC FINE PARTICLES DISPERSED IN POLYMER, Journal of magnetism and magnetic materials, 148(1-2), 1995, pp. 116-117
The de susceptibility and magnetization relaxation were investigated o
n ferromagnetic particles dispersed in a polymer matrix with different
configurations of particles in which a strong interparticle interacti
on is realized. The results suggest that intraparticle anisotropy is d
ominant in the relaxation process below 10 K, whereas the magnetic pro
perty is mainly influenced by interparticle interaction above 10 K.
