抄録

Using a scanning Hall-probe microscopy, we have developed a noncontact characterization method for multifilamentary coated conductors. In-plane distributions of sheet current density in a multifilamentary coated conductor were visualized at different conditions of external magnetic field. From these results, we could extract local critical current and equivalent width of each filament as a function of longitudinal position. These items will be indispensable for quality control of multifilamentary coated conductors and for the precise estimation of their AC losses. This means that this characterization method will be a key technology for the establishment of multifilamentary coated conductors which promise electric power applications with low AC losses.
