Magnetic Spin Lattice Relaxation Time of Liquid ³ He at Low Temperatures

Abstract

We present measurements of the magnetic spin lattice relaxation time of degenerate normal liquid 3He down to 3 mK. The results were obtained using the rapid melting technique to produce polarized liquid 3He. The measurements indicate an effective linear dependence of (T1)−1 on temperature in the intrinsic region, and are consistent with a T2-dependence in the diffusion limited wall relaxation region at the lowest temperatures. At higher temperatures good agreement is obtained with theory.
