Abstract : While recent theoretical and experimental evidence have indicated that many commonly used superconducting weak links might have distinctly nonsinusoiual current-phase relations, precise measurement of these relations has been difficult to realize. Now a high resolution technique has been developed for the measurement of current-phase relations of weak links. The authors have employed this technique to determine the current-phase relations of various weak link structures including point contacts, thin film microbridges and proximity effect bridges.
