Abstract
The importance of Castaing instabilities in θ−Δt−π spin-echo experiments in spin-polarized normal Fermi fluids is investigated. For small tip angles and very large values of the spin rotation parameter μM, a previous stability analysis is extended to account for angular relaxation, an effect which tends to reduce the growth of unstable modes. The results are compared with computer simulations and are applied to currently planned experiments at NHMFL.
