Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SE In this dissertation we have modeled the magnetic and thermal properties of rareearth intermetallic compounds by using a molecular field model. For this purpose we begin with a Hamiltonian that considers the crystalline electric field interaction and the exchange interaction between the rare earth ions treated in the approach molecular field. We developed a computer program to determine the eigenvalues and eigenvectors with which determine the magnetization, internal energy and hence the specific heat of the ...
