Abstract:
The effective Hamiltonian of the Suhl–Nakamura interaction of nuclear spins in a helimagnet has been constructed for the case where an external magnetic field is applied perpendicular to the axis of the helicoid. The contribution from the intraboundary and intradomain spin excitations to the parameter and effective radius of this interaction has been calculated. The second moment and local broadening of the NMR absorption line, which are determined by the indirect interaction of the nuclear spins, have also been calculated.
