Abstract
NiS2-2xSex is revisited to determine the magnetic structure using neutron diffraction and magnetic representational analysis. Upon cooling, the insulating parent compound, NiS2, becomes antiferromagnetic with two successive magnetic transitions. The first transition (M1) occurs at TN∼39K with Γ1ψ1 symmetry and a magnetic propagation vector of k=(000). The second transition (M2) occurs at TN∼30K with k=(0.5,0.5,0.5) and a Γ1ψ2 symmetry with face-centered translations, giving rise to four possible magnetic domains. With doping, the system becomes metallic. The transition to the M2 state is suppressed prior to x=0.4 while the M1 state persists. The M1 magnetic structure gradually vanishes by x∼0.8 at a lower concentration than previously reported. The details of the magnetic structures are provided.
