摘要
We have synthesized a new perovskite of the K2NiF4 structure Sr2VO4. The formal valence of vanadium is 4+. We have performed X-ray and neutron experiments which show that the octahedra surrounding the vanadium is elongated. The compound is insulating and antiferromagnetic. These properties are reminiscent of those of La2CuO4 which becomes a high Tc superconductor when doped, the copper d9 ion being replaced by the vanadium d1 ion. © 1990 Academic Press, Inc.
