Abstract :
The results of the effect of chromium substitution for iron on magnetocrystalline anisotropy and its temperature dependence for a series of sintered bulk Cr-substituted cobalt ferrites (CoCrxFe2-xO4 with 0lesxles0.8) over the temperature range 400 to 10 K is reported. SQUID magnetometer is used to measure major hysteresis loops at various different temperature over the range 10-400 K. It was observed that anisotropy increases with decreasing temperature, with the steepest increase coming at progressively lower temperatures for increasing Cr content.
