  We present here some newer characteristics pertaining to paramagnetic
Meissner effect like response in a single crystal of the low Tc superconducting
compound 2H-NbSe2 via a detailed study of effects of perturbation on the
field-cooled magnetization response. In the temperature range, where an
anomalous paramagnetic magnetization occurs, the field-cooled magnetization
response is found to be highly metastable: it displays a curious tendency to
switch randomly from a given paramagnetic value to a diamagnetic or to a
different paramagnetic value, when the system is perturbed by an impulse of an
externally applied ac field. The new facets revealed in a single crystal of
2H-NbSe2 surprisingly bear a marked resemblance with the characteristics of
magnetization behaviour anticipated for the giant vortex states with multiple
flux quanta predicted to occur in mesoscopic-sized superconducting specimen and
possible transitions amongst such states.
