68.55.-a - Opis:
- Layers of Sn$\text{}_{1-x}$Mn$\text{}_{x}$Te (x ≤ 0.1) with thickness 0.2-2 μm were grown by molecular beam epitaxy on BaF$\text{}_{2}$ substrates with a 0.01-1 μm thick SnTe buffer layer. Both SnTe and Sn$\text{}_{1-x}$Mn$\text{}_{x}$Te layers show metallic p-type conductivity with conducting hole concentrations (at T=77 K) p$\text{}_{77}$=7×10$\text{}^{19}$ -2×10$\text{}^{21}$ cm$\text{}^{-3}$. The layers grown under the conditions of an extra Te flux have a high carrier concentration and exhibit ferromagnetic phase transition at T$\text{}_{C}$ ≤ 7 K. The layers grown with no (or very low) additional Te flux show low carrier concentrations (below 10$\text{}^{20}$ cm$\text{}^{-3}$) and remain paramagnetic in the temperature range studied T=4.5÷70 K.
