The double perovskite $Sr_2$$CrMoO_6$ with $Cr^{3+}$$-O-Mo^{5+}$ pairs is ferrimagnetic $(T_N = 450 K)$, but there is considerable site disorder. The disorder appears to be responsible for the low value of magnetization. At 5 or 6 T, the negative magnetoresistance (MR) is <5% at all temperatures, unlike $Sr_2$$FeMoO_6$ which shows MR upto 27%. Tunneling magnetoresistance behavior of $Sr_2$$CrMoO_6$ is comparable to that of $Sr_2$$FeMoO_6$ , but the magnitude is considerably smaller in the former.
