AAg2(M'(1/3)M(2/3))[VO4]2: synthesis, magnetic properties, and lattice dynamics of honeycomb-type lattices.
The magnetic honeycomb lattice series of compounds, AAg2(M'1/3M2/3)[VO4]2 with A = Ba(2+), Sr(2+), M' = Mg(2+), Zn(2+), and M = Mn(2+), Co(2+), and Ni(2+), have been synthesized and their physical properties are reported. This series of compounds contains the M' and M cations in a 1:2 ratio on a single crystallographic site. In an ordered arrangement, this could generate a magnetic honeycomb-type lattice. Presented X-ray diffraction data, spectroscopic measurements of lattice dynamics, along with ab initio calculations, magnetic, and specific heat data for these compounds clearly point toward the formation of magnetic honeycomb-type lattices.
