摘要： Superconducting transition metal oxide films are provided which exhibit very high onsets of superconductivity and superconductivity at temperatures in excess of 40.degree. K. These films are produced by vapor deposition processes using pure metal sources for the metals in the superconducting compositions, where the metals include multi-valent nonmagnetic transition metals, rare earth elements and/or rare earth-like elements and alkaline earth elements. The substrate is exposed to oxygen during vapor deposition, and, after formation of the film, there is at least one annealing step in an oxygen ambient and slow cooling over several hours to room temperature. The substrates chosen are not critical as long as they are not adversely reactive with the superconducting oxide film. Transition metals include Cu, Ni, Ti and V, while the rare earth-like elements include Y, Sc and La. The alkaline earth elements include Ca, Ba and Sr.

摘要： A superconducting device operable at temperatures in excess of 30.degree. K. and a method for making the device are described. A representative device is an essentially coplanar SQUID device formed in a single layer of high T.sub.c superconducting material, the SQUID device being operable at temperatures in excess of 60.degree. K. High energy beams, for example ion beams, are used to convert selected portions of the high T.sub.c superconductor to nonsuperconductor properties so that the material now has both superconductive regions and nonsuperconductive regions. In this manner a superconducting loop having superconducting weak links can be formed to comprise the SQUID device.

摘要： A radio frequency (RF) multibit tag structure useful for identifying objects of interest is described. An array of thin cantilevers of slightly different lengths produced by differential etching are coated with a soft magnetic material which upon interrogation with an RF magnetic field vibrate at their resonant frequencies in the presence of an appropriate bias or direct current (DC) field. The oscillating magnetic fields generated by the vibrating bars and the stationary DC field can be readily detected by a receiver and processed to determine the code of the tag and thus provide information related to the object.

摘要： A programmable tag for being readable remotely and in a manner which does not require that the tag be held in a particular orientation, includes a first layer of material with electron spin resonance absorption, a second layer of hard magnetic material, and a third layer of soft permeable magnetic material. The second layer and third layer are in close proximity to the first layer. The second layer and the third layer impose a magnetic bias field on the first layer.

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.

摘要： A beam addressable file using as a storage medium an amorphous magnetic composition having uniaxial anisotropy. The storage medium can be prepared in thin film or bulk form or as particles in a binder. The storage medium can be comprised of a single element or a multicomponent system where at least one of the components has an unpaired spin so that the composition has a net magnetic moment. The storage comosition exists in a microcrystalline structure (i.e., it has localized atomic ordering over a distance 25-100 angstroms) and also in a substantially amorphous structure (i.e., when the composition has localized atomic ordering only over distances less than 25 angstroms). Binary and ternary compositions, either alloys or compounds, are suitable. particularly good examples are combinations of rare earth elements and transition metal elements. The magnetic properties of these amorphous magnetic compositions are easily changed during fabrication or after fabrication, and the compositions can be doped readily without adversely affecting magnetic properties. Either electron beams or light beams can be used to write information into the storage medium and optical readout is generally preferred. Curie point writing or compensation point writing is used.
