Abstract

Y₂CoRuO₆ was synthesized as a B-site ordered double perovskite with distorted monoclinic P2₁/n symmetry and an average tilting of the CoO₆ and RuO₆ octahedra of ψ = 19.7°. DC magnetization measurements show a ferrimagnetic transition at around 82 K. Although long-range ferrimagntic order is supported by neutron diffraction studies, aging phenomena in time-dependent isothermal magnetization, frequency dependence of AC susceptibility, and a smeared peak in the specific heat together reveal spin glass-like dynamics. The magnetic subtleties resemble chaotic behavior as previously observed in some ferro- or ferrimagnetic materials that exhibit spin glass-like dynamics. It is argued that the magnetic dynamics in Y₂CoRuO₆ mainly stem from competition between antiferromagnetic Co-O-(Ru)-O-Co/Ru-O-(Co)-O-Ru and antiferromagnetic Co-O-Ru interactions, besides a degree of Co:Ru antisite disorder. Herein, the B-site ordered Y₂CoRuO₆ offers a model to explore the intriguing dynamics in correlated 3d-4d transition metal double perovskites.
