要旨

A new double perovskite compound with nominal composition Y (Formula presented.) MgRuO (Formula presented.) is synthesized by the floating zone technique. X-ray diffraction measurements reveal a monoclinic crystal structure with space group (Formula presented.) and monoclinic angle (Formula presented.) = 90.178(1) (Formula presented.) as crystallographically expected for a double perovskite. A composition of Y (Formula presented.) Mg (Formula presented.) Ru (Formula presented.) O (Formula presented.) is revealed by our single crystal X-ray diffraction measurement. The magnetic susceptibility of this compound does not show indications of magnetic ordering down to the lowest temperature. A Curie–Weiss fit for the paramagnetic part above 300 K yields an effective moment that indicates an S = 1 Ru (Formula presented.) state. We attribute the occurrence of the S = 1 state and the lack of magnetic order to the presence of the (Formula presented.) -site disorder. © 2023 by the authors.
