Temperature dependence of (a) magnetization M under FC in a magnetic field of H = 5 Oe, and (b) thermo-remnant magnetization (TRM) measured along perpendicular (⊥c), 45° and parallel to c-axis (||c) of the FeF2 circular disc. The inset shows a photograph of the top view (along the c-axis) of the FeF2 single crystal used in experiment.
