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

At temperatures below 0.5T, we observed a sharp change in a shape and a duration of a free induction decay signal of sHe -B. Below thii temperature signal bears clear signs of instability. The onset temperature of thii phenomenon does not depend significantly on the pressure, the magnetic field or t

Zero sound attenuation has been used to probe vortex textures in rotating 3He-A. The highly nonlinear rotation speed dependencies of the measured sound amplitudes can be explained partly as being due to sonic velocity gradients in the vortex cores. Calculations of sound propagation in the geometrica
