Abstract: The magnetic and galvanomagnetic properties of single crystals of the new diluted magnetic semiconductor $p$-Sb$_{2-x}$Cr$_x$Te$_3$ $(0\leq x\leq0.02)$ have been studied in the temperature range 1.7–300 K. A ferromagnetic phase with the Curie temperature $T_c\approx5.8\,$K and the maximum Cr content $x=0.0215$ has been revealed. The easy magnetization axis is parallel to the $C_3$ crystallographic axis. In the presence of strong magnetic fields, the Shubnikov–de Haas effect has been observed. Analysis of this effect shows that doping with chrome reduces the concentration of holes. Negative magnetoresistance and the anomalous Hall effect are observed at liquid helium temperature.
