  Double perovskite oxides have gained in importance and exhibit negative
magnetoresistance, which is known as colossal magnetoresistance (CMR) effect.
Using a La$_2$CoMnO$_6$ (LCM) thin film we prove that the physical consequences
of the CMR effect do also influence the electron energy loss spectrometry
(EELS) signal. We observe a change of the band gap at low energy losses and are
able to study the magnetisation with chemical sensitivity by employing energy
loss magnetic chiral dichroism (EMCD) below the Curie temperature T$_C$ where
the CMR effect becomes significant.
