摘要：

Series of nanocrystalline Cu1-xZnxFe2O4 (x = 0.2, 0.4, 0.6 and 0.8) spinel ferrites have been synthesized using advanced sol-gel method. The XRD measurements confirm the formation of cubic spinel structure in single phase for all the samples and the average particle sizes are 14-18nm. In this paper the dc magnetization study for one sample Cu0.4Zn0.6Fe2O4 is reported. The nanocrystalline sample is superparamagnetic above the blocking temperature of 180 K. The reduction in saturation magnetization is attributed to disordered magnetic moments at surface around the core of nanoparticles.
