Composite Magnetic Solitons in SuperfluidHe3-A

A new type of domain wall is found where both vectors $\hat{d}$ and $\hat{l}$ rotate from parallel to antiparallel configuration in the same plane but in the opposite sense. The composite soliton has the surface energy smaller by a factor of $\sqrt{5}$ than the pure $\hat{d}$ soliton in a uniform $\hat{l}$ texture. The oscillations of the vector $\hat{d}$ in the composite soliton give rise to satellite resonance frequencies, smaller than the normal magnetic resonance frequencies in the $A$ phase.
