Metal-semiconductor transition in single crystal hexagonal nickel sulphide
TL;DR: In this paper, the authors show that the Ni 3d states are essentially localized or form a narrow band and the predominant mechanism of conduction is by holes in a wide band.
Journal ArticleDOI
Electrical and Magnetic Properties of Single‐Crystal Hexagonal Nickel Sulfide
TL;DR: In this article, electrical and magnetic susceptibility measurements have been made on five single crystals of compositions ranging from NiS to NiS1.02 in the temperature region 78°-300°K.

Mossbauer investigation of the metal-nonmetal transition in hexagonal NiS doped with 2-at% 57Fe
TL;DR: In this paper, the Mossbauer spectra of two compositions of hexagonal Ni1-xS doped with 2%57Fe were obtained at various temperatures from 4.2 to 300 K at Tc=244 K in the first and 221K in the second, a first-order phase transition occurs between an antiferromagnetic nonmetal and a paramagnetic metal; the magnetic susceptibilities, thermoelectric powers and conductivities change sharply in magnitude with a transition width of 4-5 K.
