Ferromagnetic- and superconducting-like behavior of the electrical resistance of inhomogeneous graphite flake
Abstract
We have measured the magnetic field and temperature dependence of the resistivity of several micrometers long and heterogeneously thick graphite sample. The magnetoresistance results for fields applied nearly parallel to the graphene planes show both a granular superconducting behavior as well as the existence of magnetic order in the sample.
