内容記述 | Resonant x-ray diffraction at the L-2- and L-3-absorption edges of Ru has been used to investigate the magnetic structure of Ca3Ru2O7, a material with a bilayer perovskite structure that undergoes a transition from a high-temperature metallic to a low-temperature insulating phase at 48 K. In the insulating phase, magnetic Bragg reflections characteristic of A-type antiferromagnetic order (that is, ferromagnetic RuO2 bilayers coupled antiferromagnetically along the c-axis) were identified. The azimuthal-angle dependence of the diffracted intensity implies that the magnetic moments are aligned along the b-axis in the RuO2 planes. In the metallic phase, the A-type magnetic order persists up to the Neel temperature of 56 K, but the sublattice magnetization decreases by a factor of similar to 1.7 and rotates by 90 degrees within the planes. Resonant signals characteristic of uniform or staggered orbital order were not found within the experimental sensitivity, probably reflecting a weak orbital polarization in the insulating state. | |||||
