TL;DR
This study uses X-ray magnetic circular dichroism to measure Re 5d magnetic moments in Sr2CrReO6, revealing significant spin and orbital moments consistent with band-structure calculations, and correlating Curie temperature with B' ion moments.
Contribution
It provides direct experimental measurements of Re 5d magnetic moments in Sr2CrReO6, confirming theoretical predictions and exploring the relationship between magnetic moments and Curie temperature.
Findings
Re 5d spin magnetic moment of -0.68 μ_B detected
Orbital magnetic moment of +0.25 μ_B observed
Curie temperature scales with B' ion's spin magnetic moment
Abstract
We have measured Re 5d spin and orbital magnetic moments in the ferrimagnetic double perovskite Sr2CrReO6 by X-ray magnetic circular dichroism at the L_{2,3} edges. In fair agreement with recent band-structure calculations [Vaitheeswaran et. al., Ref 1], at the Re site a large 5d spin magnetic moment of -0.68 mu_B and a considerable orbital moment of +0.25 mu_B have been detected. We found that the Curie temperature of the double perovskites A2BB'O6 scales with the spin magnetic moment of the 'non-magnetic' B' ion.
