a \({B}_{0}^{\star }\) and \({B}_{0}^{bt}\) versus temperature. The measured \({B}_{0}^{bt}\) tracks μ0DMs (with D = 0.76), which is represented by the green solid line. \({B}_{0}^{\star }\) and \({B}_{0}^{bt}\) cross each other at TA. Above this, hysteresis loops can only have a bow-tie shape for whatever Bmax, because of the \({{\rm{B}}}_{0}^{\star }\,<\,{B}_{0}^{bt}\) inequality. b \({{\rm{B}}}_{\rm{max}}^{\star }\) and \({B}_{\rm{max}}^{bt}\) versus temperature. Dashed lines are guides to the eye. TA = 115 ± 5 K, corresponds to the crossing point of \({{\rm{B}}}_{\rm{max}}^{\star }\) and \({B}_{\rm{max}}^{bt}\).
