Abstract:
A complex oxide of the Y$_2$Mn$_{2/3}$Re$_{4/3}$O$_7$ composition with pyrochlore-like structure and parameters of hexagonal unit cell $\alpha=14.91(1)$ Å, $c=17.53(1)$ Å was synthesized. The magnetic susceptibility and magnetization measurements showed that below 190 K this oxide possesses spontaneous magnetic moment. In the paramegnetic region, the magnetic susceptibility obeys the Curie-Weiss law $\chi=C/(T-\theta)$, with $C=2.07\,$cm$^3\cdot{}$K/mol$^{-1}$ and $\theta=-160$ K, and the effective magnetic moment corresponding to the cationic combination Mn$^{2+}$-Re$^{5+}$. The data obtained allow one to assume that the compound has a noncollinear antiferromagnetic structure
