    摘要: The present invention concerns the enhancement of critical current densities in cuprate superconductors. Such enhancement of critical current densities include using wave function symmetry and restricting movement of Abrikosov (A) vortices, Josephson (J) vortices, or Abrikosov-Josephson (A-J) vortices by using the half integer vortices associated with d-wave symmetry present in the grain boundary.

    摘要: In accordance with the disclosure, certain impurities, e.g., alloying additions, are introduced in thin metal film to negate the driving force or the effect of the driving force which causes the hillock formation. Such thin metallic films are usually fabricated on the substrates which have different thermal coefficients of expansion than the film itself, and during thermal cycling stresses can be introduced into the film. This stress may serve as a driving force for atom movement and, therefore, to the formation of hillocks. The vehicle by which the induced stress in a film effects the requisite atom movement is via defect movement, and when the force is compressive this gives rise to hillocks. In the practice of this disclosure, impurity additions introduced into a film affect hillock growth by their interaction with the defects which give rise to the requisite atom movement. Systematically selected impurity additions are introduced into a film during fabrication thereof which inhibit the defect movement in the class consisting of a migration of point defects, linear defects and planar defects wherein the linear defects are dislocations and the planar defects are grain boundaries. Usually, the addition of impurities into a metal film is termed alloying and the resultant film is termed an alloyed film. The alloying addition may be either soluble or insoluble in the film. This will determine the choice of possible modes of fabrication. When the alloy addition is soluble, it is included within the limits of solubility at the temperature at which it is introduced. When the alloy addition is insoluble, it is introduced during fabrication and quantity thereof may be significantly better than the quantity capable of being sustained were the alloying addition and the film to be in thermal equilibrium.

    摘要: Apparatus using amorphous magnetic compositions having uniaxial anisotropy include bubble domain apparatus, light modulating apparatus, permanent magnet systems, and tape and disc information handling systems. The amorphous magnetic composition can be prepared in thin film or bulk form or as particles in a binder. The anisotropy can be parallel to the plane of a film of this material or perpendicular to the film plane. The amorphous material is comprised of a single element or is a multicomponent system where as at least one of the components has an unimpaired spin so that the composition has a net magnetic moment. The amorphous composition exists as a microcrystalline structure having localized atomic ordering over a distance 25-100 A, or as a substantially amorphous structure where localized atomic ordering is over distances less than 25A. Binary and ternary compositions, either alloys or compounds, are suitable. The magnetic properties of the compositions can be changed during fabrication or after fabrication, and the compositions can be doped readily without adversely affecting magnetic properties.
