Abstract:
he properties of liquid $^3$He in a low-density aerogel preliminarily covered with a few monolayers of $^4$He were studied by pulsed and nonlinear CW NMR techniques. It was found that an NMR frequency shift from the Larmor value exhibits a sharp increase at a magnetization tilting angle exceeding $104^\circ$. Nonlinear CW NMR signals related to the formation of a macroscopic region featuring homogeneous precession of the magnetization (homogeneous precession domain) were observed. The experimental results confirm that the low-temperature superfluid $^3$He phase in the aerogel is analogous to the B-phase in bulk $^3$He and indicate that the spin supercurrents play an important role in the spin dynamics of superfluid $^3$He in aerogel
