Evidence of unquenched Re orbital magnetic moment in AA′FeReO6 double perovskites

Spin and orbital magnetic moments of rhenium in AA′FeReO6 double perovskites (A,A′=Ba, Sr, and Ca) have been directly probed employing x-ray magnetic circular dichroism at the Re L2,3 edges. A considerable orbital magnetic moment is observed in all the compounds studied, which confirm theoretical predictions of unquenched Re orbital moment despite its octahedral coordination. Relative orbital-to-spin moment ratio alters with lattice distortion from mL∕mS=−0.285to−0.337 from Ba2FeReO6 to Ca2FeReO6, respectively. Moreover, the spin moment of Re ion scales with Curie temperature, the most relevant property in spin electronics application of the compounds studied.
