Abstract
The effect of the carrier concentration induced shift of the g factor (the Knight shift) of the Mn2+ magnetic moment in PbTe and SnTe semico nducting matrices is experimentally observed and is of different sign for n- and for p-type crystals. The analysis of this effect allows for a straightforward determination of both the sign and the magnitude of the free carrier-local moment exchange integrals for holes and electr ons in PbTe, as well as for light and heavy holes in SnTe.
