Measurements of anisotropic mass of magnons confined in a harmonic trap in superfluid 3He-B
DOI: 10.7868/S0370274X15120061
Abstract
We can pump magnons to a nearly harmonic magneto-textural trap in superfluid 3He-B. Using the NMR spectroscopy of levels in the trap we have measured the anisotropic magnon mass and related values of the spin-wave velocities. Based on our measurements we provide values of the Fermi-liquid parameter Fa1.
