Abstract: CeCrO₃ single-phase polycrystalline samples were prepared by combustion synthesis technology. The structural, magnetic and dielectric properties of CeCrO₃ were characterized by X-ray diffractometers, field emission scanning electron microscopes and physical property measurement systems. Magnetization measurements show that the magnetic phase transition of CeCrO₃ sample occurs near 260 K. There is a linear relationship between the reciprocal of the magnetic susceptibility of the highly docile magnetic segment and the temperature, which indicates that CeCrO3 obeys Curie Weiss's law. The Curie-Weiss temperature is a negative value (−292.1 K), indicating the antiferromagnetic coupling between Cr sublattice moments. In addition, there exists magnetization reversal at 120 K, due to the interaction between weak ferromagnetic component in tilt antiferromagnetism of Cr sublattice and reverse magnetic moment of paramagnetic R sublattice due to reverse internal field polarization of Cr. The reciprocal of the dc magnetic susceptibility (1/x) varies linearly in a high temperature region, which follows the Curie-Weiss law. Magnetization reversals are attributed to the antiferromagnetic coupling between the R³⁺ moments and Cr³⁺ moments. The dielectric curves exhibit a thermal activation relaxation caused by Max, and the dispersion phenomenon was observed near 270 K. The Jonscher equation is used to fit the ac conductivity, the results show that the carrier conduction in the sample can be understood by the mechanism of correlated barrier hopping (CBH).
