75.30.Et - Opis:
- Magnetic susceptibility, electron paramagnetic resonance and transport properties of Sn$\text{}_{1-x}$Gd$\text{}_{x}$Te with 0.04 < x < 0.07 and hole concentrations in the range from 0.7 × 10$\text{}^{20}$ to 16 × 10$\text{}^{20}$ cm$\text{}^{-3}$ were investigated. After annealing of the Sn$\text{}_{1-x}$Gd$\text{}_{x}$Te samples with x < 0.05 in Sn vapor their hole concentration decreased from 5 × 10$\text{}^{20}$ cm$\text{}^{-3}$ to about 3 × 10$\text{}^{20}$ cm$\text{}^{-3}$ and their paramagnetic Curie temperature increased a few times. In samples with x > 0.05 no significant change in the magnetic properties was observed after annealing, even at lower hole concentrations. The results can be explained by assuming that an indirect exchange interaction, 4f-5d-band electrons, is responsible for the coupling among Gd ions.
