    • To reproduce the linear increase in the magnetization curve between Hc1 and Hc2, we had to assume that the sample is heated during the experiment. The heating is likely due to the magnetocaloric effect, evidenced by the smeared anomaly at Hc2 (see the upper panel of Fig. 2 in Ref.). Static-field measurements at isothermal conditions will be helpful to clarify this issue.
