摘要:
For provides a superconducting material comprising highly chemically stable Fullerene carbon molecules having a relatively high transition temperature and high chemical stability, C20 Fullerene molecules having stronger electron-lattice interaction than that of C60 Fullerene molecules are used, in order to polymerize the C20 Fullerene molecules into a one-dimensional chain, C20 is incorporated in a gap of a material having a large band gap between a valence band and a conduction band, thereafter, electrons or positive holes are injected into the obtained C20 Fullerene chain polymer via an electric field application for phase transition to a superconductor.

摘要:
A superconducting material higher in superconducting transition temperature and superconducting volume ratio than any conventional one is provided, which comprises a fullerene doped with rubidium and cesium. This fullerene system superconducting material makes it possible to improve both the superconducting transition temperature and superconducting volume ratio by having rubidium and cesium doped thereinto compared with any conventional fullerene systems. If the chemical composition of this super conducting material is expressed as Rb.sub.x Cs.sub.y C.sub.n, x and y are arbitrary if an equation x+y=3 is satisfied, preferable to be x=2 and y=1, further preferable to be x=1 and y=s. The superconducting transition temperature Tc and superconducting volume ratio when x=1 and y=2 or x=2 and y=1 are superior to those when x=3 and y=0 or x=0 and y=3, respectively.

摘要:
Methods for enhancing characteristics of superconductive fullerenes and devices incorporating the fullerenes are disclosed. Enhancements can include increase in the critical transition temperature at a constant magnetic field; the existence of a superconducting hysteresis over a changing magnetic field; a decrease in the stabilizing magnetic field required for the onset of superconductivity; and/or an increase in the stability of superconductivity over a large magnetic field. The enhancements can be brought about by transmitting electromagnetic radiation to the superconductive fullerene such that the electromagnetic radiation impinges on the fullerene with an energy that is greater than the band gap of the fullerene.
