Nickel-zinc spinel nanoferrites: Magnetic characterization and prospects of the use in self-controlled magnetic hyperthermia

Effect of zinc substitution on magnetic properties and AC heating characteristics of Ni1−xZnxFe2O4 (x = 0–1) nanoparticles has been studied. Magnetic parameters, such as saturation magnetization, Curie temperature, specific loss power, have been determined for the samples. It is shown that the samples with a higher zinc concentration (x > 0.5) display reduced values of spontaneous magnetization and Curie temperature as compared to those with x
