ABSTRACT:
An organic polymer ferromagnetic material characterized in that the material comprises a polymer obtained by subjecting to plasma polymerization or oxidation polymerization a methane derivative having two substituents and represented by the formula ##STR1## wherein A is an electron accepting group, and B is an electron donating group, or by copolymerizing the methane derivative with a diarylmethane derivative represented by the formula ##STR2## wherein R.sup.1 is a substituted or unsubstituted phenyl group by plasma polymerization or oxidation polymerization.
