(a) Plot of \(f\) as function of \(j\) for \({\alpha }_{1}=\) 0.05, 0.1, 0.3, 0.6, and 0.9, with \({J}_{1}\), \({J}_{2}\), and \({M}_{1}\) fixed to 0.6 and − 0.6 mJ/m2, and 50 kA/m, respectively. (b) Plot of \(f\) as function of \(j\) for \({M}_{1}\) = 50, 75, 100, and 125 kA/m, with \({J}_{1}\), \({J}_{2}\), and \({\alpha }_{1}\) fixed to 0.6 and − 0.6 mJ/m2, and 0.05, respectively.
