Abstract
We describe a scheme for nuclear spin maser which has an artificial feedback to the nuclear spins to bring about a self-sustained nuclear spin precession and thus to allow unlimitedly long observation times for precession. This scheme can operate under lower applied fields and smaller spin densities than the conventional spin maser scheme. Its operation was experimentally tested by using a spin-polarized 129Xe gas as a model substance. The frequency fluctuation and other basic properties were analyzed based on the modified Bloch equations.
