Two different critical regimes enclosed in the Bean-Rodbell model and their implications for the field dependence and universal scaling of the magnetocaloric effect.
TL;DR: The well-known Bean-Rodbell model is used to confirm that these features are unmistakably related to the critical behavior of the continuous phase transitions and it is concluded that it is really difficult to know with full certainty if a sample really is in the tricritical regime.
