(a) M-H loops of BaMnF₄ at T = 300 K and T = 5 K after cooling with a field of 200 Oe with the enlarged view in left inset. Right inset: the enlarged view of M-H loop measured with cooling field of −200 Oe. (b) Temperature dependence of H_E and H_C. The inset shows the enlarge view of M-H loop measured at 5 K with maximum field (H_max) of 10 kOe after cooling under field of 200 Oe. The arrow indicates the closure of hysteresis loop at H_irr. (c) Enlarged view of M-H loops measured under different H_max at 5 K after cooling under field of 200 Oe. The inset shows the dependence of H_E and H_C on H_max.
