From: Quadrupolar ordering and exotic magnetocaloric effect in RB4 (R = Dy, Ho)
Temperature dependence of the magnetic entropy change of DyB4 during various magnetic field changes of 10, 20, 30, 40 and 50 kOe; (a) parallel to the c-axis and (b) perpendicular to the c-axis. (c) Theoretical calculation of the entropy change based on the Landau free energy, which shows the agreement with the observed data in terms of the temperature and field (See the main text for more details).
