The Leggett-Rice Effect in Liquid 3He Systems
In a recent series of papers Leggett and Rice1 and Leggett2,3 showed that it should be possible to measure spin-wave effects in a Fermi liquid by using spin-echo magnetic resonance techniques. Spin-wave effects become important in a Fermi liquid in the “collisionless regime,” when ω 0 τ ≳ I, where ω 0 is the Larmor frequency and τ the quasiparticle collision time.
