掺Ag的YBaCuO高Tc超导体的研制

INVESTIGATION ON THE PREPARATION AND PROPERTIES OF THE Ag-DOPED YBaCuO HIGH Tc SUPERCONDUCTING MATERIAL

一、引言由于我们采用微分扰动角关联(DPAC)方法对超导样品的机理进行研究,必须要在样品中加入少量放射性的Ag作探针。在原有烧制工艺的基础上作了些改进,烧制出的含Ag超导样品YBa_2(Cu_(0.9)Ag_(0.1))_3O_(7-(?)),T_(?)

The YBa_2(Cu_0.9Ag_0.1)_3O_(7-8) superconductor whose T_c is 92.5K has been prepared. The percentage of superconductive ingredient in the sample is about 35%. The technique used for preparing the sample is interpreted tentatively. The sample has been investigated by using differential perturbated ansular cor-retation(DDAC) method. The experimental results are discussed.
