Abstract
In some samples of SnTe:Gd the measured paramagnetic Curie temperature strongly depends on the Fermi level position. The semi-quantitative theory which explains this effect is presented. The theory is based on Kasuya's model of exchange interaction between two 4f spins of rare earth ions. In this model the interactioii between 4f electrons and the valence band goes via Gd atomic 5d orbitals which, contrary to the 4f orbitals are much more extended in space. The exchange integral and the paramagnetic Curle temperature dependence on the Fermi level position are calculated. PACS numbers: 71.70.Gm, 75.30.Et, 75.30.Ηx
