Abstract
The magnetic and electronic structure of the colossal magnetoresistance (CMR) Fe0.5Cu0.5Cr2S4 are studied. The Fe, Cu, and Cr ions in the compound are consistently tri-, mono-, and trivalent, respectively. The key feature in the electronic structure that is of significance to the magnetism, is the finding that majority Cr states polarize the band structure and minority Fe states are found as a result at the Fermi energy. These chalcogenides demonstrate that GMR materials are the magnetic counterpart of superconductors.
