Abstract
We consider spontaneous magnetic flux in an annular s-wave/normal meta l/d-wave superconductor (SND) Josephson junction. The flux magnitude i s not quantized and is determined by the parameters of the system. In an isolated system, quantum fluctuations of the superconducting phase take place, leading to quantum flux noise. The possibilities of experi mental observations of the effect are discussed.
