Spin-glass behavior in the S=1/2 fcc ordered perovskite Sr2CaReO6
Abstract
The ordered perovskite Sr2CaReO6 of monoclinic symmetry [space group P21/n,a=5.7556(3) Å,b=5.8534(3) Å,c=8.1317(4) Å,β=90.276(5)° at T=4 K] has been synthesized using standard solid-state chemistry techniques. The difference in the size and charge of the cations induces an ordering of the B site Ca2+ and Re6+ ions which leads to a distorted fcc lattice of spin-12 Re6+ (5d1) moments. dc magnetic susceptibility measurements indicate a maximum at …
