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 Au2Mn2-zAlz where 0.1<z<0.5, preferably 0.3.

A superconductive composition having the formula:
- N2(MxZy)2
- where N is a metal, the metal characterized in having;
- (i) broad conduction electron band and
- (ii) low effective electron mass
- M comprises one or more magnetic species;
- Z is a non-magnetic diluent to the magnetic species,
- wherein x+y are substantially 1, and wherein magnetic moments of the magnetic species are correlated over a relatively long range.
The superconductive composition of claim 6 wherein the noble metals are chosen from the group consisting of copper, gold and silver.
The superconductive composition comprising in combination;
- a metal, the metal characterized in having;
- (i) broad conduction electron band and
- (ii) low effective electron mass, and
- one or more magnetic species
- characterized in that the magnetic moments of the magnetic species are ferromagnetically correlated, and a structure to induce long range correlation of the magnetic species.
