Probing the ground state magnetic structure of single crystalline Mn2V2O7

Abstract: Mn2V2O7 exhibits reversible structural transition from the high temperature monoclinic phase (C2/m) to low temperature triclinic phase (P-1) near room temperature where Mn2+ ions form regular and distorted honeycomb network respectively. An antiferromagnetic like transition below 20 K as well as magnetic anisotropy were observed in this compound. We performed powder neutron diffraction measurement and this data fitted well with commensurate propagation vector (0,0.5,0) between 12 K and TN =20 K and Mn2+ shows the antiferromagnetic allignment. But below 12 K the magnetic structure is still to be explored where splitting of magnetic peaks indicates incommensurate structure and it is nontrivial to determine based on powder data. Hence, we propose here to carry out single crystal neutron diffraction study on Mn2V2O7 which is important to explicitly solve the ground state magnetic structure.
