Abstract
The demagnetization processes occurring at different angles in Perpendicular Exchange-Spring Fe-FePt bilayers grown on MgO (100) by RF sputtering were investigated. Fe53Pt47 thin films of nominal thickness 10 nm constituted the hard phase while a Fe layer deposited at RT with various thicknesses (from 2 nm up to 10 nm) was the soft one. The angular dependence of their magnetic properties was studied by means of Superconducting Quantum Interference Device (SQUID) varying the angle between the hard phase easy-axis and the direction of the applied field from 0 to π/2. A one-dimensional micro magnetic model was developed and applied to those systems in order to simulate and compare theoretical and experimental results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
