Transport phenomena in spin quantum wells (SQW) are studied based on narrow‐gap magnetically mixed semiconductors. In contrast to compositional quantum wells, the depth of SQW is easily changed under the action of temperature or magnetic field, which leads to a change in the concentration of quasi‐two‐dimensional electrons in SQW. It is shown that in this case the coefficients of transverse magnetoresistance and thermoelectric power display non‐monotonic dependence on temperature and magnetic field.
