TLDR
A 2CrReO6 (A=Sr and Ca) was found to be a metallic ferromagnet with a high Curie temperature (TC=635 K), possibly the highest-TC half metal among the perovskite family as mentioned in this paper.Abstract:
Electric, thermal, optical, and magnetic properties have been investigated for ferromagnetic (ferrimagnetic) ordered double perovskites, A2CrReO6 (A=Sr and Ca) Sr2CrReO6 is found to be a metallic ferromagnet with a high Curie temperature (TC=635 K), possibly the highest-TC half metal among the perovskite family By contrast, Ca2CrReO6 is a ferromagnetic Mott insulator with TC of 360 Kread more

Intergrain tunneling magnetoresistance in polycrystals of the ordered double perovskite Sr2FeRe06
TL;DR: In this paper, the first-principles band calculation predicts that the half metallic ground state with the ferrimagnetic coupling of Fe and Re spins is obtained for polycrystalline ceramics with Curie temperature above 400 K. The experimental results of electronic and magnetic properties are in accord with this picture.
