  We have studied experimentally the responses of high quality single crystals
of stoichiometric synthetic magnetite to applied weak dc and ac magnetic fields
in the range of 6 K to 60 K, far below the Verwey transition. The results can
be compared to so called Magnetic After Effects (MAE) measurements, which are
the most extensive magnetic measurements of magnetite at these temperatures. We
present a novel point of view on the relaxation phenomena encountered at these
temperatures - the Low Temperature Anomaly, addressing the striking difference
between the results of conventional ac susceptibility measurements and those
accompanying MAE measurements, i.e. periodic excitations with strong magnetic
pulses. We also draw a connection between this anomaly and the so called
glass-like transition and discuss possible mechanisms responsible for these
effects.
