Query: Electric Contributions to Magnetic Force Microscopy Response from
  Graphene and MoS2 Nanosheets   Magnetic force microscopy (MFM) signals have recently been detected from
whole pieces of mechanically exfoliated graphene and molybdenum disulfide
(MoS2) nanosheets and magnetism of the two nanomaterials was claimed based on
these observations. However, non-magnetic interactions or artefacts are
commonly associated with MFM signals, which makes the interpretation of MFM
signals not straightforward. A systematic investigation has been done to
examine possible sources of the MFM signals from graphene and MoS2 nanosheets
and whether the MFM signals can be correlated with magnetism. It is found that
the MFM signals have significant non-magnetic contributions due to capacitive
and electrostatic interactions between the nanosheets and conductive cantilever
tip, as demonstrated by electric force microscopy (EFM) and scanning Kevin
probe microscopy (SKPM) analyses. In addition, the MFM signals of graphene and
MoS2 nanosheets are not responsive to reversed magnetic field of the magnetic
cantilever tip. Therefore, the observed MFM response is mainly from electric
artefacts and not compelling enough to correlate with magnetism of graphene and
MoS2 nanosheets.
