Cu, Pu and Fe high Tc superconductors: all the same mechanism!

arXiv:0806.0900

Abstract

The new iron based high Tc superconductors with Tc up to 55 K have stirred new interest in this field. It is consensus that the BCS mechanism is not able to explain the high Tc's. In the following we propose that spin holes in antiferromagnetic clusters combine to make nonmagnetic bipolarons, which can condense and lead to superconductivity.
