The crystal structure,magnetism,and colossal magnetoresistance of Y2CrS4

Ternary yttrium chromium sulfide,Y2CrS4,prepared by the solid-state reaction of Y2S3,Cr,and S,was found to exhibit an antiferromagnetic transition at about 64 K.The X-ray diffraction pattern at 300 K was refined with space group Pca2 1,and the structure parameters were determined to be a = 12.51 Ab...

Summary:Ternary yttrium chromium sulfide,Y2CrS4,prepared by the solid-state reaction of Y2S3,Cr,and S,was found to exhibit an antiferromagnetic transition at about 64 K.The X-ray diffraction pattern at 300 K was refined with space group Pca2 1,and the structure parameters were determined to be a = 12.51 Ab = 7.53A,and c = 12.49A,We investigated the magnetotransport properties,and observed negative colossal magnetoresistance reaching up to 2.5 × 10^ 4 % in the semiconducting compound of Y2CrS4.
