1. PROPRIEDADES TÉRMICAS E MAGNÉTICAS DOS BOROCARBETOS / THERMAL AND MAGNETIC PROPERTIES OF A SERIES OF BOROCARBIDES
We propose a spin hamiltonian to describe the magnetic and thermal properties of a series of borocarbides. The effect of the crystal electric field is simulated by an effective magnetic field. By applying spin wave theory we have found the dispersion relation and the density of state for the magnos as well. In presence of an external magnetic field this dens
