Abstract:

As seen in the c-w NMR experiments of undd 3He, at least three magnetic domains each having the anisotropic axis perpendicular to each other always seem to coexist in single crystals. We first determine the structure of the magnetic domain walls taking into account the exchange interaction, the dipole interaction and an applied magnetic field. Next we study scattering of spin waves by the domain wall and show that spin waves with small wave number k≪ξD-1, where ξD is the dipole length, are almost totally reflected by the dipole potential near the wall. This result can be related to the NMR experiments: The spin precession in a resonant domain is in general not coupled to spins in other non-resonant domains, which may provide a plausible explanation for the observed coexistence of three sharp NMR peaks.
