Pulsed excimer laser deposited Co- and Fe-based magnetic films for fast magnetic sensors
Abstract
Magnetic films were prepared by pulsed KrF excimer laser ablation of amorphous magnetic ribbons and permalloy foils in vacuum of (2-4)×10-5 Pa. Films were analysed by XRD, RBS, EDX and FMR. The films deposited from ribbons are amorphous, permalloy films have the grain size of approximately 5 nm. Fe and Fe+Ni rich films have low magnetization motion damping parameter and they are expected to be suitable for fast magnetic sensors.
