Abstract: The present invention relates to a metal-halide composite, articles comprising a metal-halide composite and method of making and using same. The metal-halide matrix materials used in such composite have the desired properties of high thermal conductivity, resistance to thermal induced microstructural changes, and ease of use. As a result, they permit the fabrication of higher performance cryogenic magnets, motors, generators, and cables. Additionally, they permit the fabrication of plate reinforced composites that are useful in lightweight armor and other articles. Additionally, an optoelectronic composite could be built depending on the choice of metal-halide matrix and reinforcement.

Abstract: The present invention provides a method of making a high temperature superconductor having a doped, nanoparticulate pinning structure. The method includes providing a nanoparticulate pinning material, providing a cuprate material, doping the nanoparticulate pinning material with a dopant to form a doped nanoparticulate material, depositing a layer of the cuprate material on a substrate, and depositing a layer of the doped nanoparticulate material on the layer of cuprate material. The invention also provides a high temperature superconductor (HTS) having a doped, nanoparticulate pinning structure including a plurality of layers of a cuprate material and a plurality of layers of a doped nanoparticulate pinning material. At least one layer of the doped nanoparticulate pinning material is stacked between two layers of the cuprate material.

Abstract: A method for enhancing the flux pinning of a YBCO superconductor by substituting minute quantities of rare earth elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) or other deleterious elements (Sc, etc.) for Y in YBCO thin films is described. The method of the present invention enables enhanced flux pinning of the material while not significantly increasing the cost of the HIS material and can be used in all HTS deposition methods since it is not process dependent.

Abstract: A method of manufacturing a high temperature superconductor is disclosed. The method includes depositing, by pulsed laser deposition, alternating layers of YBa2Cu3O7-x (Y123) and Y2BaCuO5-y (Y211). The Y211 layers are characterized by a multiplicity of nanosized globular inclusions, effectively enhancing flux pinning and thus increasing current transport.
