Superstructure formation and magnetism of synthetic selenian pyrrhotites of Fe7(S1-ySey)8, y≤1 composition

Abstract

Synthetic pyrrhotites of composition Fe-7(S1-ySey)(8) were synthesized at 423 and 873 K and then quenched in cold water. It is shown from X-ray diffraction and indirectly from Superconducting Quant ...
