Abstract
⺠Co1âxNix/2Srx/2Fe2O4 (x=0-0.5) nanoparticles were prepared by a reverse micelle method. ⺠Ni and Sr enter preferably at site B and substitution of cobalt does not change the magnetic hyperfine field at the site A much. ⺠Good agreement with the experimental data of susceptibility. ⺠Vogel-Fulcher model confirms the existence of strong interactions between nanoparticles.
