Crystal, magnetic and dielectric studies of the 2D antiferromagnet: β-NaMnO2
Crystal, magnetic and dielectric studies of the 2D antiferromagnet: β-NaMnO2
In this paper we present our recent studies on the crystal, magnetic and dielectric properties of the β-NaMnO2. Experimental results of neutron powder and electron diffraction combined with measurements of the dielectric permittivity suggest that the β-NaMnO2 is an excellent candidate for studying the coupling between the magnetic and electric degrees of freedom. Neutron powder diffraction data reveal the existence of a commensurate and an incommensurate magnetic structure at 200 K and below 100 K, respectively. Dielectric anomalies which appear at the temperature regions where the two magnetic structures emerge, indicate the appearance of magnetodielectric coupling.

Abstract
In this paper we present our recent studies on the crystal, magnetic and dielectric properties of the β-NaMnO2. Experimental results of neutron powder and electron diffraction combined with measurements of the dielectric permittivity suggest that the β-NaMnO2 is an excellent candidate for studying the coupling between the magnetic and electric degrees of freedom. Neutron powder diffraction data reveal the existence of a commensurate and an incommensurate magnetic structure at 200 K and below 100 K, respectively. Dielectric anomalies which appear at the temperature regions where the two magnetic structures emerge, indicate the appearance of magnetodielectric coupling.
