Spin-polarized electron transport in the high-pressure ferromagnetic   phases (GaSb)$_2$M (M=Cr,Mn)
  For the first time magnetrotransport of the ferromagnetic high-pressure phases of (GaSb)$_2$M (M=Cr,Mn) was measured. It was found that the main component of magnetotransport in these phases is negative and its amplitude is increasing with temperature rising and approaching Curie temperature. Measuring of magnetoresistance in the cycling magnetic fields demonstrated that the Yosida component of magnetresistance is negligible and the main part of the magnetoresistance can be attributed to the spin-polarized electron transport.
