Magnetic and Magnetoresonance Properties of Multilayered Systems Based on (CoFeB)x-(SiO2)100-x Composite Layers

Article Preview

Abstract:

Magnetic properties and ferromagnetic resonance data of (Co41Fe39B20)x-(SiO2)100-x composite films and multilayer structures composed of these films separated by SiC interlayers have been studied. It has been shown that one of the possible causes responsible for the differences of magnetic properties of composites and multilayer structures can be different shapes of magnetic particles and granules in these materials.
