Abstract :
We report on the preparation and characterization of the variation of B′-site transition metal in Sr2CrMO6 (M=Mo, W) with double perovskites structure. The magnetic susceptibility shows that Sr2CrMoO6 and Sr2CrWO6 are antiferromagnets with TN=40 and 30 K at H=1 T, respectively. In addition, a large magnetoresistance ratio (MR) of ∼38% (H=3 T) at 5 K was observed in the Sr2CrWO6 compound. However, the Sr2CrMoO6 compound does not show any significant MR even at high fields (MR∼4%; H=3 T and 5 K). The measured O K-edge X-ray absorption is in agreement with the calculated O p-density of states for both compounds.
