Abstract : In this work, we observed a steady trapped magnetic flux in thin graphite flakes obtained from bulk highly
oriented pyrolytic graphite (HOPG). Magnetization curves of the finely ground graphite flake sample after cooling down
from 300 K to 10 K in the magnetic field of 1 T revealed the non-zero additive magnetic moment with the sign
corresponding to the applied magnetic field during the field cooling. This additive magnetic moment is stable with respect to
an exposure of the sample to the magnetic field of 1T which might indicate the presence of the superconducting phase
inclusion in the sample that reveal itself via the trapped fluxes. In addition to magnetic measurements morphological and
structural properties of the sample are also reported.
