AAg2(M鈥?sub>1/3M2/3)[VO4]2: Synthesis, Magnetic Properties, and Lattice Dynamics of Honeycomb-Type Lattices
文摘
The magnetic honeycomb lattice series of compounds, AAg2(M鈥?sub>1/3M2/3)[VO4]2 with A = Ba2+, Sr2+, M鈥?= Mg2+, Zn2+, and M = Mn2+, Co2+, and Ni2+, have been synthesized and their physical properties are reported. This series of compounds contains the M鈥?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.
