Les propriétés magnétiques des composés spinelles M1/2In1/2Cr2X4 où M = Cu ou Ag et X = S ou Se ont été examinées. Dans le cas des sulfures, les moments de Cr sont ordonnés antiferromagnétiquement avec TN = 40 °K dans le cas M = Cu et TN = 17 °K dans le cas M = Ag. Aucun ordre magnétique à grande distance n'est observé à 4 °K pour Cu1/2In1/2Cr2Se4, tandis que le composé M = Ag est ferromagnétique en dessous de Tc ≈ 60 °K. La structure magnétique de Cu1/2In1/2Cr2S4 a été déterminée par diffraction des neutrons. Elle est bâtie à partir de quatre sous-réseaux d'aimantation parallèles aux grandes diagonales du cube.The magnetic properties of the spinels M1/2In1/2Cr2X4 with M = Cu or Ag and X = S or Se were investigated. In the sulphides the ...
