Popis:	A low frequency ac measuring‐current technique has been used to investigate the magnetoresistance and Hall effect in Hg1−xMnxTe over a temperature range from 2 to 300 K. The exchange interaction between the Mn++ ions and the band carriers causes the energy bands to be significantly modified in the presence of a magnetic field. As a result magnetic boil‐off and magnetic‐field‐enhanced hopping have been observed in p‐type semiconducting samples. These effects produce a large decrease of resistance with increasing magnetic field at low temperatures.
