Abstract
We present the synthesis of AgLnMo2O8 compounds with Ln = La-Nd and Sm. These compounds represent a scheelite-type structure characterized by MoO4-tetrahedrons. IR spectra show five absorption peaks in the region of 1000-400cm−1, around 800cm−1 and 400cm−1, which correspond to the modes of the tetrahedral MoO2−4 groups. All of AgLnMo2O8 (Ln = La-Nd and Sm) oxides are dielectric materials at room temperature. The temperature dependence of the magnetic susceptibility of AgLnMo2O8 (Ln = Ce-Nd and Sm) shows Curie-Weiss law behavior from 100K to 300K. This indicates that both Ce and Pr exist in +3 oxidation state in AgLnMo2O8. For AgLaMo2O8, diamagnetic properties are found as expected.
