a Measured isothermal Mc at T = 2, 10, 20, 30, 35 and 45 K. The Mc data are shifted vertically for clear visualization. The marked scale denotes 1 μB/f.u. The inverted triangles indicate occurrence of Hflop at each T. b Measured isothermal Mb at T = 2, 10, 20, 30, 35 and 45 K. c Measured (solid curves) and calculated (dotted curves) isothermal Mc in the low Hc regime at T = 30, 31, 32 and 33 K. d Hc derivative of the measured Mc at T = 30, 31, 32, and 33 K. The inverted triangles denote occurrence of spin-flop transitions, Hflop = 0.32, 0.28, 0.24 and 0.18 T for T = 30, 31, 32 and 33 K, respectively. e Measured (closed circles) and calculated (dotted curves) H dependence of the magnetic torque, τ, taken at θ = –4° for T = 30, 31, 32, 33 and 34 K. f Dark green and light green circles plotting the T dependence of the interlayer exchange coupling energy (JS2) and MCA energy (\({\rm{K}}\)) divided by JS2, respectively.
