Abstract :
The resistivity and the optical absorbtion spectra of single crystal α-MnS are studied in the temperature range 80–300 K along two directions [100] and [111]. Strong anisotropy of the resistivity, and the shift of absorbtion spectra band edge below T<160 K are explained in terms of model involving delocalized holes in 3d-band manganese ions interacting with localized spins by using the sd-model.
