Thickness Dependence of Amorphous CoSiB/Pd Multilayer with Perpendicular Magnetic Anisotropy

Magnetic Properties of Exchange-Biased Multilayer With Perpendicular Magnetic Anisotropy

Perpendicular exchange-biased and multilayers have been fabricated, changing the thickness of the cobalt that is next to the IrMn layer. The crystal structure, interface roughness and magnetic properties were characterized by X-ray diffraction (XRD), X-ray reflectivity (XRR), atomic force microscopy (AFM) and extraordinary Hall Effect (EHE). The multilayers are flat, and the roughness is about ...

The Perpendicular Magnetic Anisotropy of CoPt/Au Multilayer Films

We have studied the magnetic properties of Au (2 nm)/Co50Pt50 (3 nm)/Au (2 nm) multilayer films prepared on amorphous Al2O3/Si and (0 0 1) MgO substrates. The as-deposited films on both substrates are magnetically soft with an FCC structure and exhibit a perpendicular anisotropy. After annealing at 500 °C, the sample on the Al2O3/Si substrate has become magnetically isotropic but the sample on ...

Observation of thickness dependence of magnetic surface anisotropy in ultrathin amorphous films.

Ferromagnetic resonance (FMR) and SQUID magnetometry measurements have been made on multilayers of amorphous FeioB30/Ag. The dependence of the magnetic surface anisotropy constant K, on the magnetic layer thickness 2L has been determined in the range 1.6 A ( 2L & 90 A using more than twenty samples. It is found that K, is constant for 2L ) 16.S A, but decreases monotonically towards zero as 2L ...
