Two-step Mott transition in Ni(S,Se)_{2}: μSR studies and charge-spin percolation model

Two-step Mott transition in Ni(S,Se)_{2}: μSR studies and charge-spin percolation model

A pyrite system NiS_{2−x}Se_{x} exhibits a bandwidth controlled Mott transition via (S,Se) substitutions in a two-step process: the antiferromagnetic insulator (AFI) to antiferromagnetic metal (AFM) transition at x∼0.45 followed by the AFM to paramagnetic metal (PMM) transition at x∼1.0. Among a few...
