Abstract:

Formation of unidirectional exchange anisotropy has been studied during thermomagnetic treatment of permalloy-manganese bilayers. It has been found that, starting from the annealing temperature of 230 degrees C, there is observed a shift of the hysteresis loop. The maximum value of the exchange bias field is achieved after annealing at 250 degrees C for two hours and amounts to 155 Oe. Using electron microscopy, it has been demonstrated that the effects of the occurrence of unidirectional exchange anisotropy and of increase in the coercive force are due to the appearance of an ordered antiferromagnetic phase NiFeMn, which is formed as a result of diffusive interaction between permalloy and manganese upon annealing.
