Description
Highlights: • Evolution with temperature and composition of magnetizations and magnetic susceptibilities. • Influence of the crystallographic ordering on the magnetic and transport properties. • Temperature and field dependences of magnetoresistivities. - Abstract: The Ca1.5La0.5FeMo1−xWxO6 double perovskites with x ⩽ 0.3 crystallize in a monoclinic structure having space group P21/n. The degree of crystallographic ordering is increased as the tungsten content is higher. As a result, there is an increase of both saturation magnetizations and Curie temperatures. The magnetic susceptibilities follow temperature dependences typical for a ferrimagnetic system. The valence states of iron and molybdenum ions as well their distributions in the lattice sites were determined. These data were correlated with magnetic and transport properties
