Low temperature deuteron irradiation effect on type II superconductors noting atomic displacement, resistivity increase and transition temperature decrease
Limited instability and flux jumping variation with magnetic field for flux pinning and Lorentz forces equilibrium in mixed state of type II SUPERCONDUCTOR
Linear current-voltage characteristics in type II SUPERCONDUCTORS under flux flow conditions
This paper examines photoemission measurements of the alkaline Earth core levels of high-temperature superconductors and related materials, models that seek to explain the large negative shifts observed relative to the corresponding alkaline Earth metals, and the effect of lattice site disorder on the core level spectra and the presence or absence of intrinsic surface peaks.
This report, concluding a one-year NIAC Phase I study, describes a new structural and mechanical technique aimed at reducing the mass and increasing the deployed-to-stowed length and volume ratios of spacecraft systems. This technique uses the magnetic fields generated by electrical current passing through coils of high‐temperature superconductors (HTSs) to support spacecraft structures and deploy them to operational configurations from their stowed positions inside a launch vehicle fairing.
We report scanning tunneling spectroscopic studies of the effects of quantum impurities in cuprate superconductors.
A superconductor cylinder, charged with a high magnetic field, can be used to create a similar field in a larger cylinder. The uncharged cylinder is precooled, lowered into a helium dewar system, and fitted around the cylinder with the magnetic field. Magnetic flux lines pass through the two cylinders.
