Saturation and anisotropy effects of magnetization in practical composite superconductors. [NbTi]
This paper presents detailed magnetization measurements as well as an analysis on typical cryostable NbTi composite conductors (1-mm diameter and Cu/SC ratio of 6:5) with filaments nonuniformly distributed in both circular and rectangular cross sections (aspect ratio approx. 2:1). As a result of the excellent agreement between the measurements and a previously reported transformer model, both transient magnetization and losses incurred in each sample can be described by functions of a unique time constant tau/sub 0/, which depends strongly on the shape of the cross section. Other prominent features of the measurement results, such as the deduction of values of J/sub c/ and matrix resistivity, are demonstrated.
