摘要：

We report a phase sensitive technique for measuring the voltage noise of junctions which enables us easily to separate out the low frequency 1/f noise component due to critical current fluctuations. We illustrate this technique with detailed voltage noise measurements in three junctions grown by a biepitaxial process. We also provide evidence that these fluctuations are not due to motion of magnetic flux in or near to the junction.
