Theoretical investigation on the anisotropic magnetocaloric effect: Application to DyAl2

Using a simple model Hamiltonian, the formulation of the anisotropic MCE was introduced and the calculations performed for DyAl2 leads to quantitative values of ΔSiso[0 0 1][1 0 0]. An anomalous MCE was also predicted when the magnetic field is applied along the non-easy magnetization direction [0 0 1].
