Abstract
The electronic structure of paramagnetic iron is calculated self-consistently within the local spin density functional formalism by applying the coherent potential approximation with the muffin-tin potential model. The effective exchange parameters Jn are calculated as the interaction energy between two magnetic moments in the paramagnetic medium obtained. A discussion on the magnetism of iron above the Curie temperature is presented using the Heisenberg model with the calculated Jn.Keywords
