Hari Babu, N and Kambara, M and Shi, YH and Cardwell, DA and Tarrant, CD and Schneider, KR (2002) Comment on 'processing and microstructure of single grain uranium-doped Y-Ba-Cu-O superconductor'. Superconductor Science and Technology, 15. pp. 1474-1475. ISSN 0953-2048

We comment on the paper by N Hari Babu et al. (2002 Supercond. Sci. Technol. 15 104-10) and point out misinterpretations of the chemical composition of U-bearing deposits observed in Y123. The observed small deposits are those of new compounds which do not contain Cu, rather than refined Y211 plus U, as stated by the authors. We further note that extensive literature, not quoted, is in disagreement by nearly an order of magnitude concerning the values of Pt and U doping at which the optimum value of Jc is obtained. Other related information, presently in the literature, which may be helpful to those working with this high temperature superconducting chemical system, is presented.
