Comparative Raman scattering study of Ba₃MSb₂O₉ (M=Zn, Co and Cu)
Raman spectroscopy is combined with lattice dynamic calculations to investigate the magnetic and structural properties of the 6H-perovskite compounds Ba₃MSb₂O₉ (M = Zn, Co and Cu). Unlike the nonmagnetic Ba₃ZnSb₂O₉ compound, the magnetic counterparts Ba₃MSb₂O₉ (M = Co and Cu) show both lattice anoma...
