Abstract :
Zn doped cobalt ferrites Co1-xZnxFe2O4 (x = 0.0, 0.1, 0.3) powders were synthesized by chemical co-precipitation method. Phase formation and crystalline nature was verified by using X-ray diffraction and Raman spectroscopy. The saturation magnetization (Ms), coercivity (Hc) and remanent magnetization (Mr) was recorded using vibrating sample magnetometer at room temperature. Magnetostriction measurements carried out reveals that the spinel ferrite samples investigated in the present studies seems to be suitable for magnetic field sensor applications. The magnitude and signature of magnetostriction is found to be direction dependent. These ferrites hold the promise of being used as magnetic sensors.
