Evidence of Cooperative Effects for the Fe(phen)₂(NCS)₂ Spin Crossover Molecular Complex in Polyaniline Plus Iron Magnetite.

ABSTRACT: The spin crossover complex Fe(phen)₂(NCS)₂ and its composite, Fe(phen)₂(NCS)₂, combined with the conducting polymer polyaniline (PANI) plus varying concentrations of iron magnetite (Fe₃O₄) nanoparticles were studied. A cooperative effect is evident from the hysteresis width in the plot of magnetic susceptibility multiplied by temperature versus temperature (χmT versus T) for Fe(phen)₂(NCS)₂ with PANI plus varying concentrations of Fe₃O₄ nanoparticles. The hysteresis width in the composites vary no more than 2 K with respect to the pristine Fe(phen)₂(NCS)₂ spin crossover crystallites despite the fact that there exists a high degree of miscibility of the Fe(phen
