Low dimentional magnetic properties of compounds belonging to the CrVO4-type structure — •Joseph M. Law1,2 and Reinhard K.

Compounds with the ABX4 composition exhibit a range of different magnetic properties. In recent years we have concentrated on only those adopting the CrVO4-type structure, where we have a magnetic atom occupying the A position and a diamagnetic only atom within the B position. The A atom is housed within a distorted octahedral environment, the AO6 units are edge sharing and form buckled ribbon chains along the c-axis. The B atoms are contained within tetrahedral Oxygen environments which bridge the ribbon chains.
We are present first results on the magnetic properties of some selected of this series which show, multiferroic behavior, spin-Peierls transitions and conventional long-range magnetic ordering.
