RCL model for the development of hysteresis in superconductors
Abstract
A model is introduced to explain the development of hysteresis in superconductors in which heating effects can be ignored. The model is based on the transient phenomena that occur in RCL circuits at the instant the emf is turned off. We show that hysteresis develops when the total current (applied plus transient) exceeds the critical current I sub c (T). The model predicts several hysteretic behaviours that have been observed, and others that have not yet been experimentally observed. For the effect of temperature on the development of hysteresis we show that it is an aiding factor rather than a principle parameter. Under any operating condition the model predicts a maximum hysteresis width equal to 1/2 I sub c (T).
