Abstract A Monte Carlo simulation of patch-domain formation and domain coarsening in antiferromagnetically coupled compensated multilayers with fourfold in-plane anisotropy is presented. The simulation accounts for both the emergence of small patch domains on unsaturation and the domain coarsening on spin flop. The autocorrelation function of the simulated domain pattern is in good agreement with published Kerr microscopic images. Author Keywords: Domain growth; Domain pattern variations; Multilayers; Magnetic coupling??antiferromagnetic Article Outline round bullet, filled References Enlarge Image (20K) Fig. 1. Primary (a, b) and secondary (c, d) domain formation. In primary domain formation black and white pixels represent top layer rotation to the left and right, respectively, grey pixels being still in saturation. The easy axes of the fourfold anisotropy are along [1 0 0] and [0 1 0]. The sample had been saturated in the [1 0 0] direction. The grid is 500×500 pixels. The smoothing widths of the primary and secondary distributions are w1=10 and w2=100, respectively. In (c) and (d), the system during and after the spin flop is shown. The spin flop is induced by an increasing field along the [0 1 0] direction. Note that the secondary large domains are perpendicular to the primary small ones. Grey-scale scheme in (d): light grey pixels: top layer up, dark grey pixels: top layer down. Note that the scale was fitted to the Kerr image measured by Rührig et al. on a thick Fe/Cr trilayer [7 <#bib7>] and not to the domains observed by SMR on a Fe/Cr multilayer of 20 periods [5 <#bib5>].
