Concentration Dependences of Exchange Fields in Composite and Multilayer Thin Films

Monolayer composite, multilayer composite-composite and multilayer composite-semiconductor films were investigated. Dependencies of the internal exchange fields on magnetic metal alloy concentration in nanostructured single and multilayer films at room and liquid nitrogen temperatures were obtained. The calculation is made on the basis of the experimental data and the relationship of the exchange interaction and the broadening of the FMR line.
