Study of the possibility of using Ni-Fe-Mn alloys as material for pinning layers in spin valves

Magnetic properties of nanostructures based on Ni80Fe20/(Ni80Fe20)1 − x Mn x bilayers are studied at various compositions and thicknesses of the antiferromagnetic (AFM) layer. The possibility of using triple compounds based on Ni-Fe-Mn in spin valves is considered. Regularities of the formation of unidirectional anisotropy in permalloy/manganese bilayers during thermomagnetic treatment are revealed.
