| Popis: | We present nmr measurements in a 6.2% 3 He- 4 He mixture carried out at 11.3 T with temperatures down to 3.5 mK, yielding a very high B/T ratio. We have measured the transverse spin diffusion with the spin-echo technique, We observe a saturation of the spin diffusion coefficient at low temperature corresponding to an anisotropy temperature T a ≃13mK. Using the same setup, we were able to excite Silin spin-wave modes in the experimental cell. |
