Abstract
The crystal structure, magnetic and electrical transport properties of SrKFeWO 6 double perovskite have been investigated. The structure of this double perovskite compound is assigned to monoclinic system with space group P2 1/ n and structural analysis suggests that cationic Fe and W alternately occupy B′- and B′′-sites. Thermal magnetization demonstrates that the magnetic transition temperature is higher than 500 K. Isothermal magnetization shows that the net magnetic moment per unit formula in the direction of the magnetization is 0.72 μ B (300 K). The electrical transport process can be described by non-adiabatic small polaron hopping model at low temperature, while the electronic transport behavior at high temperature is described by adiabatic small polaron hopping model. Large magnetoresistance, − 0.89, can be observed under low magnetic field, 0.5 T, around room temperature.
