In the upper panel, dipolar parameter is Jd = 0.00934 and the anisotropy parameter is K = 0.2 (c). Jd = 0.00962, 0.01004 in b and a while anisotropy parameter K remains the same as the one in c. Anisotropy parameter K = 0.1, 0.2 in d and e while dipolar parameter remain the same as the one in e. In the lower panel, Jd = 0.00962 and K = 0.2. The local coefficients from the left to the right are \(T=\frac{7}{8},\frac{7}{9},\frac{2}{3},\frac{1}{2},\frac{1}{3}\), respectively. Red arrows in h–j represent the first jump for energy curve with n = 5. The corresponding magnetic fields are hx = 10.3, 9.2, 6.9. All results are calculated with the number of sites N = 216.
