Abstract

We investigated the magnetic properties of the ilmenite-type manganates MgMnO3 and ZnMnO3, both of which are composed of a honeycomb lattice of magnetic Mn4+ ions. Both compounds show antiferromagnetic order with weak ferromagnetic moments. In particular, MgMnO3 exhibits a magnetization "reversal" behavior which can be described by the N-type ferrimagnetism in the Néel's classification. The relationship between the magnetic properties and the crystal and magnetic structures probed by the neutron diffraction experiments indicates that the two honeycomb lattice magnets have different J1-J2 parameter sets, placing them in the distinct regions in the phase diagram; both nearest neighbor (NN) and next nearest neighbor (NNN) exchange interactions are antiferromagnetic in MgMnO3, while NN and NNN interactions become ferromagnetic and antiferromagnet, respectively, in ZnMnO3.
