Abstract

The first-principles calculations of electronic structure and a number of thermodynamical characteristics were performed for layered magnetic superconducting systems RNi2B2C, RFe4Al8 and FeSe in the normal state. The analysis of electronic states and interactions responsible for the structural and magnetic properties of the investigated systems was carried out.
