Resumen
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]. © 2008. 320 14 e143 e146 Tishin, A.M., Spichkin, Y.I., (2003) The Magnetocaloric Effect and Its Applications. first ed., , Institute of Physics, Bristol and Philadelphia Pecharsky, V.K., Gschneidner Jr., K.A., (1997) Phys.
