a–f Hysteresis loops at 10 K, 70 K,110 K, 120 K, 130 K, 150 K, all with an identical maximum sweeping magnetic field (Bmax = 0.5 T). Note the emergence of a bow-tie feature above 120 K. g–l Hysteresis loops at T = 10 K with different maximums sweeping fields (Bmax = 5 T, 1 T, 0.35 T, 0.3 T, 0.25 T and 0.1 T). When Bmax becomes smaller than 0.35 T, a bow-tie feature emerges.
