| Abstract: | Based on the Heisenberg model including single-site uniaxial anisotropy and using aGreen’s function technique we studied the influence of size and composition effects on theCurie temperature T C , saturationmagnetization M S and coercivityH C of spherical nanoparticles with astructural formulaM e 1?x Zn x Fe2O4,Me = Ni, Cu, Co, Mn. It is shown that for x = 0.4–0.5and d = 10–20 nm these nanoparticles have aT C = 315 K and are suitable for aself-controlled magnetic hyperthermia. |
