The Shubnikov‐de Hass effect (SdH) is investigated in n‐type Hg l−x Mn x Te mixed crystals for several compositions in the range 0.02 ≦ x ≦ 0.04. Experiments are carried out on samples with electron concentrations between 2 × 10 15 and 8.5 × 10 17 cm −3 at temperatures from 2 to 25 K. Prom the temperature dependence of the amplitude of the SdH oscillations the effective masses of electrons are determined. The data are analyzed in terms of a model developed to account for anomalies observed earlier in the SdH effect in this material.
