The effect of surface barriers to flux entry on the stability of superconductors at low fields is considered theoretically in the context of the usual critical-state model. The presence of such a barrier is found to greatly reduce overall stability unless a thin normal-metal overcoat is used to stabilize the superconductor. The relevance of these results to superconducting power transmission lines is discussed.
