Abstract:

The formation of the ordered NiFeMn antiferromagnetic phase in the course of thermomagnetic treatment of manganese-permalloy bilayers has been investigated. The influence of the type of substrate, number of layers, and modes of thermomagnetic treatment on the magnetic properties of the films is studied. It has been shown that the maximal effect of unidirectional anisotropy associated with the presence of the ordered NiFeMn ferromagnetic phase in ferromagnetic layers is attained at an annealing temperature of 260 degrees C for 4 h. The shift in the magnetic hysteresis loop with a thickness of the switched layer of about 40 nm is 380 Oe, while the blocking temperature is congruent to 270 degrees C.
