Spin-Wave Resonance Detection of Nanostructured Magnetic Alloy Inhomogeneities, Using the Example of Co–P and Co–Ni Planar Systems

Resumo

Inhomogeneous layered magnetic thin films of amorphous and nanocrystalline Со–Р and Co–Ni alloys are studied via spin-wave resonance. It is found that the formation of a magnetic potential profile specified over the coating thickness leads to characteristic modifications of the spin-wave resonance spectrum. Another important factor that determines the type of modification is the dominant magnetic parameter (the constant of magnetization or exchange coupling).
