The paper "The Mean-Field Theory for the Study of the Magnetocaloric Effect of Nd0.67Ba0.33Mn0.98Fe0.02O3 Manganite" has been published in Journal of Superconductivity and Novel Magnetism

Here  you will find Michel Boudard's paper

"In this paper, we exploit the mean-field theory and the Bean-Rodbell model to justify the magnetocaloric effect (MCE) on Nd0.67Ba0.33Mn0.98Fe0.02O3 manganite. The modeling of magnetic properties was investigated. The Bean-Rodbell equation of state leads the system to second-order ferromagnetic (FM)-paramagnetic (PM) phase transition. The expressions describing the magnetic entropy change under the influence of magnetic field have been derived. A large magnetic entropy has been observed in our sample with a peak centered on the Curie temperature. The theoretical calculations are compared with experimental behavior."
