TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1969 A brief review is presented on the ac losses of superconductors in the low-frequency, high-frequency, and weak-field regions. Special emphasis is given to the hysteresis loss which is the main part of the low frequency losses. Existing data of the low-frequency losses are collected to be shown in a single figure and it is shown that most of these can ...

Current distribution and AC losses in twisted multifilamentary AC superconductors [PDF]
IEEE Transactions on Magnetics, 1989 The development of AC superconductors has led to multifilamentary wires having a highly resistive matrix material and a small twist pitch and filament diameter. A numerical one-dimensional model is presented which enables the authors to calculate the current distribution as well as the magnetization and transport current loss in a current-carrying AC ...
