Abstract
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.
Claims21
A method for enhancing one or more superconductive characteristics of superconductive fullerenes comprising transmitting electromagnetic radiation comprising ultraviolet light, visible light, or infrared light to the superconductive fullerenes, the electromagnetic radiation impinging upon the superconductive fullerenes with an energy that is greater than the band gap of the superconductive fullerenes, wherein the superconductive fullerenes are hydrogenated and intercalated and have the general structure of:
- CsaRbbKcMyCnHx
- in which M=Hg, Bi, or Tl
- a, b, c=0-3,
- y=0-2,
- wherein at least one of a, b, y is at least 1
- n is 20 or greater, and
- x=about 10 or more.
