Homogeneously precessing domain in 3 He − B: a tool for studying graphene

Homogeneously precessing domain (HPD) can by observed in NMR experiments in superfluid He − B. HPD is characterized by coherent precession of magnetization with large tilting angle stabilized by superfluid spin currents. This state is a good tool for studying properties of 3 He − B. We have developed a 3 He NMR setup using a dry cryostat and performed some preliminary measurements. At present, we are preparing an experiment for probing superfluid coherence across graphene membrane immersed in 3 He by means of the HPD. I will tell about this work and about preliminary measurements in a one-volume cell where we have found some new interesting features of the HPD.
