文摘

Co magnetic anisotropies (cubic and uniaxial) controlled by film growth parameters. Co uniaxial magnetic anisotropy depends on in-field and/or oblique deposition parameters. Co uniaxial strength is determined by oblique deposition angle value. Co cubic magnetic anisotropy only dominates when the substrate spinning is higher than 40 rpm. Two magnons scattering process is responsible for the FMR line broadening behavior.
