We identify an onset of superconductivity at T~0.7 K in both the real and imaginary components of the susceptibility which is confirmed by resistivity data. A superconducting volume fraction argument, based on a comparison with a calibration YBCO sample, indicates that the superconductivity in these samples may be filamentary. Our data also demonstrate the sensitivity of the coplanar micro-magnetometers, which ","authors_text":"A.R. Hamilton, C.H. Mielke, D.G. Rickel, D.J. Reilly, J.C. Cooley, J.L. O'Brien, J.L.
