Zeisberger, M and Campbell, AM and Lo, W and Cardwell, DA (1997) Characterization of YBCO Bulk samples by local AC-susceptometry. IEEE Transactions on Applied Superconductivity, 7. pp. 1065-1068. ISSN 1051-8223

Melt processed HTSC bulk samples usually show a high inhomogeneity. These inhomogeneities influence application-relevant properties such as the lévitation force or the trapped field. In this contribution a technique is presented which allows investigation of these inhomogeneous properties. The measurements are performed by scanning the sample surface with a small coil system and detecting the first and third harmonic of the inductive response. The critical current density jc is calculated from the measured signal using a modified critical state model. Jcdistributions yielded by this technique are shown. © 1997 IEEE.
