The measurement of cw NMR absorption in a homogeneously precessing spin domain of sHe-B is discussed. The absorptron is divided into several contributions, based upon their drfferent dependences on the domain length. Within our experimental accuracy, we found no contribution linear with domain size

Superfluid counterflow in rotating vortex-free sHe-B induces distinct changes in the homogeneously precessing resonance domain: its volume is reduced and the NMR absorption increased. Both effects disappear if the domain fills the whole experimental cell.
We present new experimental and theoretical studies of magnetic relaxation in 'He-B. Methods are developed for the measurement of relaxation using either CW or Pulsed NMR. Both methods make use of the properties of the Homogeneously Precessing Domain. Terms corresponding to intrinsic (Leggett-Takagi
