โœฆ Synopsis

In order to determine the solid solubility of Ag in YBa2Cu306+v and its effect on superconducting properties, a series oi" YBa2Cu3_ ~AgxO6+ v samples (x_ < 0.75 ) have been prepared and characterized by X-ray diffraction, optical microscopy, and electron microprobe analysis. The central results arc that Ag goes into solid solution up to about x=0.06 and that initially (up to x=0.035 ) superconducting properties are improved -T,. goes up by 1.1 K, intragrain critical current density is marginally improved and Meissner effect is considerably enhanced. However, at higher x all the superconducting propcrties are considerably degraded. The implication of these results on the usc of Ag as a cladding material for 123 or in a composite arc discussed.

The effects of double CuO2 layers in YBa2CuaO6+x for 0 < x < 1 were studied critically. For x= 0, the superexchange interaction through Y enhances the antiferromagnetic exchange interaction between the intralayer nearest-neighbor sites and the interlayer third-nearest neighbor sites. As a result, su

Significant reduction in the magnitude of thermal conductivity of a sample of YBa=~CusOv-v (YB~) has been observed when the sample was stored in dry air for a period of one year, though it was reoxygenated to restore superconductivity. A modified BRT type analysis points to an increase in point defe
