Magnetoresistance and magnetic properties measurements of CuxZn1-xFe2O4 system

A systematic study of longitudinal and transverse magnetoresistance in CuxZn1-xFe2O4 system with x = 0.0, 0.25, 0,50, 0.75, 1.0 has been carried out to find out the optimal highest resistive state for practical applications. The variation in magnetoresistance is of the first-order effect as in semiconductors. The effect of compositional variation on saturation magnetization, remanence and coercivity at room temperature are also reported. It has been observed that the highest resistive state appears at the field value for which the saturation magnetization exists for each concentration. (C) 2002 Elsevier Science B.V.
