Temperature dependence of the total magnetization and the component of the magnetization along the ⟨100⟩ direction. The Dashed line is the spontaneous magnetization. Inset shows the temperature dependence of the angle. A strong jump occurs around .
Temperature dependence of the magnetic entropy changes . There exist a valley at around for applied along the ⟨100⟩ direction. The inset displays the temperature dependence behavior of entropy for and along the ⟨100⟩ direction.
Temperature dependence of the magnetic entropy variation for , 1.3, 3.4, and along the ⟨100⟩ direction. Inset shows the calculated as function of temperature for magnetic field change from applied in the ⟨100⟩ direction. At there is an anomalous valley.
Temperature dependence of the magnetization component along the ⟨100⟩ direction for some values of . The inset shows the phase diagram .
