Four samples of YBCO doped with cobalt have been characterised using several techniques, including measurements of Tc, AC susceptibility, resistivity, magnetic susceptibility, and yttrium nuclear magnetic resonance (nmr). The last two techniques were

The authors report nuclear magnetic resonance data at high magnetic fields up to 13 T on superconducting samples of yttrium barium copper oxide, with oxygen content close to seven atoms per formula unit. Both free powder and aligned (at room temperat

The authors have carried out extensive NMR measurements in a Tl-Sr-Ca-Cu-O system as a function of y, the yttrium/calcium concentration, over the stoichiometry range encompassing the metal-superconductor-(antiferromagnetic)semiconductor transition. T

Aircraft observations of the microwave emission from the wind-driven foam-covered Bering Sea substantiate earlier results and show that the combination of surface roughness and white water yields a significant microwave brightness temperature depende

The current available in situ data on the physical characteristics of the 90-130 km environment depends on sounding rocket and maneuverable satellite systems for its collection. Such data are, of necessity, sporadic in both time and space. The develo

Microwave and infrared data were obtained from a research aircraft over the Beaufort Sea ice from the shoreline of Harrison Bay northward to a latitude of almost 81 deg N. The data acquired were compared with microwave data obtained on the surface at

Because of the high data-rate requirements, a practical system capable of collecting seismic information in the field and relaying it, via satellite, to a central collection point is not yet available. A seismic signal processor has been developed an

A field reconnaissance was carried out near Green Bank, West Virginia, to assess the possibility that active faults might produce movements which would introduce errors to geodetic results of Very Long Baseline Interferometry (VLBI) measurements carr
