Crystallographic and magnetic structures of the new honeycomb material BaCo2-xMgx(AsO4)2 (x=0, 0.1, 0.3)
BaCo2(AsO4)2 is a compound comprising a honeycomb lattice of magnetic Co2+ ions. It exhibits exotic magnetic properties, with an incommensurate magnetic order below 5 K, which is still not fully understood. In particular, it displays anisotropic in-plane magnetic correlations lengths, which remain unexplained so far as no structural distortion of the honeycomb planes has been reported. Moreover, recent neutron inelastic measurements reveal magnetic excitations incompatible with an incommensurate magnetic order, thus highlighting discrepancies between the static and dynamic properties. In order to further understand these discrepancies, we propose to disturb the magnetic ground state and study the effect of non-magnetic substitution in the newly synthesized compounds BaCo2-xMgx(AsO4)2 (x = 0, 0.1 and 0.3) and perform a detailed temperature dependence study of the structure and magnetic propagation vector.
