Abstract
Analytical formulas derived by Norris [J. Phys. D 3 (1970) 489] and Brandt et al. [Phys. Rev. B 48 (1993) 12893] are often used to calculate the AC transport current and magnetization losses in HTS strip conductors. In those formulas, homogeneous distribution of critical sheet current density Ïc in the strip is assumed. However, it is considered that Ïc in actual HTS strips are distributed inhomogeneously and that deviations of the measured AC loss data of actual HTS strips from those formulas are due to the inhomogeneous Ïc distributions. We derived a semi-analytical method to calculate the transport current and magnetization losses in an HTS strip with inhomogeneous Ïc distribution. The validity of the semi-analytical method is shown by comparing the experimental and analytical data.
