Peculiarities of the Magnetocaloric Effect in an Isotropic Antiferromagnet
Abstract:
It is shown that the magnetocaloric effects are absent in the spin-flop phase of an isotropic antiferromagnet at the T<TN (TN the Neel temperature) and appear only when an applied magnetic field exceeds the critical field of the spin-flip transition. It is displayed as well that the direct magnetocaloric effects in an antiferromagnet above TN are much less that the analogous effects in a ferromagnet above the Curie point TC.
