Abstract
Temperature-induced sign reversal of magnetization in the vicinity of room temperature is reported in a single-phase spinel compound of Ni(Cr0.70Fe0.30)2O4. The magnetic compensation temperature is 358 K. The mechanism of magnetization reversal is explained by considering the different temperature dependences of sublattice magnetization. Bipolar switching of magnetization at room temperature is demonstrated by just varying the magnetic field from + 200 to + 2050 Oe, i.e., without changing the direction of the magnetic field. Tunable positive and negative exchange bias fields are observed in the vicinity of room temperature with a maximum value of 1 kOe.
