Magnetic Resonance in [(CoP)(soft)/NiP/(CoP)(hard)/NiP] (n) Multilayer Magnetic Springs

The magnetic resonance properties of [(CoP)_soft/NiP/(CoP)_hard/NiP]_n multilayer films with the properties of magnetic springs have been experimentally studied. It has been found that the deposition of a NiP nonmagnetic amorphous layer on a (CoP)_soft magnetic layer induces the appearance of perpendicular interface anisotropy. The increase in the number of blocks n in the multilayer structure leads to the appearance of the third absorption peak, which is explained by the formation of a noncollinear three-sublattice magnetic structure.
