Abstract

Characteristic temperatures in ferromagnetic-antiferromagnetic exchange biased systems are analyzed. In addition to usual blocking temperature of exchange bias, T-B, and the Neel temperature of an antiferromagnet, T-N, the inducing temperature of exchange bias, T-ind, has been recently proposed. T-ind is the temperature at which the direction of exchange anisotropy is established. We demonstrate that this temperature is, in general, different from T-B and T-N. Measurements of T-ind, in addition to T-B and T-N, provide important information about exchange interactions in ferromagnetic-antiferromagnetic heterostructures.
