Abstract

A new class of novel super high temperature superconductive compositions and structures (SHTC), named Schrieffer Superconductors are disclosed. These superconductive compositions and structures preferably include a combination of (1) a metal, the metal characterized in having (i) a broad conduction electron band (or bands) and (ii) a low effective mass, and (2) magnetic species, wherein the spins of the magnetic species are correlated at relatively long distances. Preferably, the spins of the magnetic species are magnetically ordered ferromagnetically over relatively long range. One preferred composition is Au?2#191Mn?2-z#191Al?z#191 where 0.1 < z < 0.5, preferably 0.3.
