title: Magnetoresistance of the high-pressure ferromagnetic phases (GaSb)2M (M=Cr,Mn).
abstract: For the first time magnetoresistance of the ferromagnetic high-pressure phases (GaSb)2M (M=Cr,Mn) has been measured in a wide range of temperature and magnetic field. It was found that the magnetic field dependencies of resistivity of both systems contain several contributions, including relatively smaller s-d exchange (Yosida-type) components in low fields and a quadratic positive term (PMR) in the low temperature region. The magnitude of the predominated negative term (NMR), which can be attributed to the quantum corrections effects, demonstrates a peak in the vicinity of Curie temperature.
