摘要

The magnetic properties of tilted easy axis L1(0) 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 K-1 = 5 x 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.
