摘要

Fe3-xZnxO4 (x=0.2, 0.4, 0.6, 0.8, 1) nanoparticle with average diameters of 12 nm was produced by our novel wet chemical method. The crystal structure and magnetic property of the obtained particle were investigated by X-ray diffraction and superconducting quantum interference device (SQUID) magnetometer. Direct current (DC) magnetization measurement showed that the coercive force Hc and saturation magnetization Ms decreased as the composite parameter x increased. This phenomenon suggests that Zn2+ ions located on tetrahedral A sites weaken the superexchange interaction between tetrahedral A and octahedral B sites. From the alternative current (AC) magnetic susceptibility, a sample with composition of x=0.4 is expected for heating by external field. Temperature increase depending on the magnetic field strength and frequency supported that samples with composition of x=0.2, 0.4 were appropriate for use as an agent in hyperthermia treatment.
