Antiferromagnetic Spin

New mechanism of superconductivity is presented, which utilizes antiferromagnetic spin waves. It is found that for the case of Ising like anisotropy the spin wave coherence strongly enhances the superconductive coupling constant, which gives rise to a rather high critical temperature. Sloppy spin wave mechanism is also suggested.

ABSTRACTAs Bednorz and Muller noted in their original publication reporting on the discovery of high temperature superconductivity, their oxides present many of the features of granular superconductors. This behavior was first primarily ascribed to poor connectivity of the grains in the bulk ceramic samples. but later studies have pointed out to more fundamental reasons for these similarities. We will discuss them after first reviewing the well established properties of low Tc granular superconductors.
