Evidence of cooperative effect in Fe(phen)2(NCS)2 plus polyaniline plus iron magnetite composite

Molecular complex of Fe(phen)2(NCS)2 plus polyaniline plus iron magnetite showed an unperturbed cooperativity upon the addition of polyaniline, which is a semiconducting polymer added to the system in an effort to reduce the overall on state resistance. Apart from that, the coupling between the iron magnentite and spin crossover complex is antiferromagnetic. This is different from the case of Fe[(Htrz)2(trz)](BF4) plus polyaniline plus iron magnetite, where the iron magnetite is ferromagnetically coupled with the spin crossover complex.
