  This work reports, some of the features related to the room temperature
superparamagnetic behaviours of lead nanoparticles. Such behaviours have not
been discussed elaborately, in any literatures, so far. It is obvious from our
studies that the superparamagnetic behaviours of Pb nanoparticles are
surprising behaviours, since bulk Pb has diamagnetic behaviours. Hysteresis
curve from Vibrating Sample Magnetometer study of Pb nanopowder (metal) serves
some new observations. The successful calculations of values like magnetic
size, saturation magnetization, coercive field, and remanent magnetism confirm
its superparamagnetic nature and explore its potential application in various
industries. This work throws some light on and helps further research.
