The photoemission spectra of NiS in both antiferromagnetic and Pauli paramagnetic phases show similar characteristic features of localized d electrons. This finding is in contrast with the results of band-structure calculations which predict drastic spectral changes between the two phases. It is suggested that fluctuations of the Ni 3d local moments due to hybridization with S 3p states near the Fermi level are responsible for the Pauli paramagnetic behavior.
