Abstract:
The powder of Ni(0.40)Zn(0.60)Fe(2)O(4) nanoparticles is synthesized using a microwave-assisted combustion method. X-ray diffraction and IR spectrum analysis show that the sample has a single-phase spinel structure. Debye-Scherrer formula reveals a crystallize size of 49 nm plus or minus 5 percent, whereas transmission electron microscopy (TEM) results show particle sizes in the range of 10 to 60 nm. uperparamagnetic nature of the sample was confirmed from a close hysteresis loop. The Curie temperature (T sub(C)) was found to be 422 degrees C and 30 K as a blocking temperature.
