Abstract

ac-susceptibility and neutron-diffraction experiments show that Fe0.4Mg0.6Cl2 is a three-dimensional Ising spin-glass with a transition temperature Tsg = 3.4 K. Inelastic-scattering experiments show a sharp spin-wave peak at the zone center for all temperature T~<2Tsg. This is the first direct observation of long-wavelength excitation in a spin-glass system. We suggest that it is due to the precession of spin clusters around the easy axis.
