Abstract
In this study, effects of Pt spacer and Co reference layers thickness in [Co/Pt]6/Pt/Co multilayer have been revealed to tailor magnetization directions in non-collinear configuration. Magneto-optic Kerr effect and ferromagnetic resonance techniques were employed to investigate magnetic properties. Bilinear coupling between [Co/Pt]6 and Co layers and anisotropy constants were determined by a micromagnetic simulation based on metropolis algorithm. 3nm spacer causes ferromagnetic coupling while the samples have 4 and 5nm spacer are coupled anti-ferromagneticaly. Also, tuning magnetic anisotropy of [Co/Pt]6 layer was accomplished by Co reference layer. It is revealed that controlling of non-collinear states in such systems is possible by variation of thickness of spacer and reference layers and [Co/Pt]6/tPt/tCo trilayer system can be used in multilayered magnetic systems.
