High-Temperature Thermal Cycling Effect on the Irreversible Responses of Lattice Structure, Magnetic Properties, and Electrical Conductivity in CoFeO Spinel Oxide.

We report high-temperature synchrotron X-ray diffraction (SXRD), magnetization, and current-voltage (-) characteristics for the samples of CoFeO ferrite. The material was prepared by chemical reaction of the Fe and Co nitrate solutions at pH ∼ 11 and subsequent thermal annealing. Physical properties of the samples were measured by cycling the temperature from 300 K to high temperature (warming mode) and returning back to 300 K (cooling mode).
