Superradiance in spin systems is studied theoretically on the basis of a microscopic model corresponding to nuclear magnets with dipole spin interactions. The onset of pure superradiance is shown to be caused by nonsecular spin interactions. While the effective interaction of spins through the common radiation field, as well as the resonator thermal-noise field, are not able to initiate coherent self-organization resulting in superradiance.
