according to Ashcroft & Mermin, "Solid State Physics", only the magnetic
moment of a neutron couples to the electronic spin in the solid.
Much more important is the neutron-nucleus interaction which is
frequently used in determining phonon spectra. Neutrons used for
these scattering experiments typically have energies from 0.1 - 0.001

Kind regards,
