  Quasielastic neutron scattering has been utilized to investigate the
Griffiths phase induced by an axial magnetic field in FeCl2 at temperatures
Tc(H)<=T<=TN, where Tc(H) is the transition temperature in an external magnetic
field H. We present the temperature dependence of the integrated neutron
scattering intensity at fixed scattering vectors for various magnetic fields.
On cooling below TN the antiferromagnetic short-range fluctuations decrease due
to an increase of the volume fraction which is already antiferromagnetically
ordered. A weighted average of the local contributions to the antiferromagnetic
susceptibility quantitatively describes the scattering cross section.
