摘要：

Based on the Heisenberg model including single-site uniaxial anisotropy and using a Green's function technique we studied the influence of size and composition effects on the Curie temperature T-C, saturation magnetization MS and coercivity H-C of spherical nanoparticles with a structural formula Me1-xZnxFe2O4, Me = Ni, Cu, Co, Mn. It is shown that for x = 0.4-0.5 and d = 10-20 nm these nanoparticles have a T-C = 315 K and are suitable for a self-controlled magnetic hyperthermia.
