CALCULATION OF EXCHANGE INTEGRALS OF VOLUME MAGNETIC CRYSTAL STRUCTURES Fe, Co, Ni AND CrNb<sub>3</sub>S<sub>6</sub>
The results of calculations of magnetic moments and exchange integrals of bulk magnetocrystalline structures Fe, Co, Ni, and CrNb<sub>3</sub>S<sub>6</sub> using the SPR-KKR package are presented. The influence of various crystal structures and approximations of the exchange-correlation potential is investigated.
