Pulsed excimer laser deposited Co- and Fe-based magnetic films for fast magnetic sensors

Magnetic films were prepared by pulsed KrF excimer laser ablation of amorphous magnetic ribbons and permalloy foils in vacuum of (2-4) x 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. (C) 2003 Elsevier B.V. All rights reserved.
