Perpendicular magnetism in magnetic multilayer systems

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 ...

Magnetic Force Microscopy of Nanostructured Co/Pt Multilayer Films with Perpendicular Magnetization

We present the results of magnetic force microscopy investigations of domain structures in multilayer [Co (0.5 nm)/Pt (1 nm)]₅ thin film structures (denoted hereafter as Co/Pt) modified by additional Co capping layers and by ion irradiation. It is demonstrated that a Co capping layer essentially changes the domain structure and decreases the threshold of magnetization reversal, due to the forma...
