| Abstract | The magnetic properties of tilted easy axis L10 CoPt(1 1 1)/Pt(1 1 1)/MgO(1 0 0) film, deposited by pulsed laser deposition, were investigated by magnetization angular dependence measurements and magnetic force microscopy (MFM). The room temperature anisotropy constant, evaluated measuring the in-plane variation of transverse magnetization under a rotating magnetic field, is K1 = 5 × 10 6 erg cm −3 . The domain structure, observed by MFM, consists of decoupled single domain grains, unlike the maze-like structure usually observed for similar systems. This was confirmed by the analysis of dc demagnetization and isothermal remanence magnetization curves, which provided evidence of predominant magnetostatic interactions. |
