Magnetic Relaxation in SuperfluidHe3near the Critical Temperature

Abstract

Longitudinal magnetic relaxation in superfluid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ as described by the theory of Leggett and Takagi is observed for particular geometries within a very limited range of $H_0$ and $1-\frac{T}{T_c}$. Other observations demonstrate that, under certain conditions, the longitudinal magnetization in superfluid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$-$A$ does not relax monotonically in time.
