Soliton lattice in superfluidHe3-A

Abstract

High-density composite solitons in superfluid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$-$A$ form a regular one-dimensional lattice. The magnetic-resonance frequencies and the intensities of these soliton lattices are determined theoretically. Furthermore, if the soliton lattice has open ends, the soliton lattice relaxes by uncoiling the $\hat{l}$ and $\hat{d}$ vectors. The characteristic time for the uncoiling is calculated. The present theory appears to account for unusual NMR behavior in magnetization-tipping experiments.
