Flow dependence of spin susceptibilities in superfluid3He

The flow dependence of spin susceptibilities in superfluid ³ He-A and -B is studied theoretically. It is shown that in the A phase _A, the component of the static spin susceptibility parallel to , increases rapidly in the presence of mass current. A similar behavior is found for all components of _B, the susceptibility tensor of the B phase.Work supported by the National Science Foundation under grant No. DMR76-21032.Recipient of a scholarship from the Studienstiftung des Deutschen Volkes.
