Modified BCS mechanism of Cooper pair formation in narrow energy bands of special symmetry II. Matthias rule reconsidered
Ekkehard Krüger
In part I of this paper a modified BCS mechanism of Cooper pair formation of electrons was proposed. This mechanism is connected with the existence of a narrow, roughly half-filled…

Modified BCS mechanism of Cooper pair formation in narrow energy bands of special symmetry I. Band structure of niobium
Ekkehard Krüger
The superconductor niobium possesses a narrow, roughly half-filled energy band with Bloch functions which can be unitarily transformed into optimally localized spin-dependent Wanni…
