Abstract

Abstract : Magnetic, dielectric and magnetoelectric properties of the polycrystalline Co4 NbTaO9 have been investigated in this paper. Abstract : Magnetic, dielectric and magnetoelectric properties of the polycrystalline Co4 NbTaO9 have been investigated in this paper. The antiferromagnetic phase transition of this compound is identified at the temperature of 23.6 K. Anomalies in the temperature-dependent dielectric constants and pyroelectric currents emerge around its magnetic transition point under magnetic field, and increase with the increasing external magnetic field. Antiferromagnetic fluctuation and domain effect are considered to be response for the phenomenon observed in this compound.
