Effect of Temperature on the Structural and Magnetic Properties of CuFe2O4 Nano Particle Prepared by Chemical Co-Precipitation Method

摘要

The behaviors of the CuFe2O4 nano particle prepared by chemical co-precipitation have been studied. The XRD result of the as dried and samples calcined at different sintering temperature has shown that the single phase has been observed in the as dried condition and there is no observation of extra peak. The grain size has been obtained from Scherrer's formula and found as 4nm to 56nm for the CuFe2O4 nano particle sample with the systematic variation of sintering temperature. Nano particle has been characterized to understand the magnetic properties from the observation of hysteresis loops.The initial permeability varies with sintering temperature due to the variation in kinetics of diffusion which depends on the particle size of the starting material. The Curie temperature has been measured from the result of temperature dependent initial permeability.
