Tuning Magnetic Properties Polycrystalline of PtCo Alloys Films with Pt

We experimentally investigated disordered PtxCo1-x (here x: 0.4, 0.5 and 0.6) alloy thin films magnetic properties which depended on Pt content. The magnetic properties of PtCo films were described with two effects, one of them is the hybridization between Co 3d and Pt 5d energy levels and it causes...

Zusammenfassung:	We experimentally investigated disordered PtxCo1-x (here x: 0.4, 0.5 and 0.6) alloy thin films magnetic properties which depended on Pt content. The magnetic properties of PtCo films were described with two effects, one of them is the hybridization between Co 3d and Pt 5d energy levels and it causes Pt magnetic polarization. The second one is the high spin orbit coupling constant of Pt which increases the ratio of magnetic orbital moment to spin moment. We investigated magnetic properties considering these effects by vibrating sample magnetometer (VSM) and ferromagnetic resonance (FMR) techniques.
