| Abstract: | The magnetic and crystal structures of the metallic sulfospinels Cu0.45Co0.55Cr2S4 - xSex have been investigated for x = 0, 0.42 and 1.0 by neutron powder diffraction techniques. The data have been analyzed by the Rietveld method. All three compositions show ferrimagnetism at low temperatures with a chromium moment of (2.7±0.1)μB and a cobalt moment of (2.8±0.1)μB. The Curie temperature varies from 293 to 253 K. |
