Abstract

Abstract:

Double perovskite LaPbMnSbO₆ was synthesized by two-step semi-chemical method, and the crystal structure and magnetic properties have been investigated. The crystal structure has been solved by X-ray diffraction (XRD) data in the monoclinic space group P2₁/n (No.14). The MnO₆ and SbO₆ octahedra are rock-salt ordered over the B-site of the perovskite structure. Due to the existence of Pb²⁺ ions, second-order Jahn-Teller effect is occurred and the lattice distortions are anisotropic in the interior of BO₆ octahedra. The magnetization curves show a typical antiferromagnetic ordering, with an antiferromagnetic ordering transition temperature at T_N=9 K.

Key words: double perovskites, two-step semi-chemical, structure refinements, magnetic properties
