Textures and NMR in superfluidHe3−(B)

Abstract

In this paper we discuss in detail the nature of the spatial variation of the order parameter of the $B$ phase of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$. It is shown that in this phase there is a single vector component of the order parameter which undergoes spatial variation under normal circumstances and the detailed nature of its variation is calculated for cylindrical and parallel plate geometries. The effect of these textures on nuclear magnetic resonance is discussed and it is shown that the textures should allow one to observe standing spin waves as well as the line-shape effects discussed in an earlier letter.
