Inelastic neutron scattering experiments are reported to study magnetic excitations in a single crystal of the reentrant spin glass Fe(0.7)Al(0.3) near the (111) Bragg peak. In the ferromagnetic phase, the magnetic excitation spectrum is separated in two areas: at low q, spin waves are propagating and at higher q, the response is quasielastic-like. In the spin glass phase, the response is always quasielastic.
