Abstract

A new layered perovskite vanadium oxide Sr4V3O8-d was synthesized and its crystal structure and magnetic properties were studied. Sr4V3O8-d has a novel crystal structure, containing a V-0 octahedron and a two-fold V-0 fence in a unit cell. It exhibits negative magnetization below 30 K. when cooled in a magnetic field. This peculiar magnetism is attributed to N-type parasitic ferrimagnetism.
