We argue using first principles calculations that there is a finite occupation of minority- spin states at the Fermi level throughout the series Co1-xFexS2.

Although the exchange-correlation functional influences the specifics of the electronic structure, we observe a similar trend with increasing Fe concentration in both LDA and GGA calculations.
