Solution-Processed Multiferroic Thin-Films with Large Magnetoelectric Coupling at Room-Temperature.

ABSTRACT: Experimental realization of thin films with a significant room-temperature magnetoelectric coupling coefficient, α_ME, in the absence of an external DC magnetic field, has been thus far elusive. Here, a large coupling coefficient of 750 ± 30 mV Oe^-1 cm^-1 is reported for multiferroic polymer nanocomposites (MPCs) thin-films in the absence of an external DC magnetic field. The MPCs are based on PMMA-grafted cobalt-ferrite nanoparticles uniformly dispersed in the piezoelectric polymer poly(vinylidene fluoride-co-trifluoroethylene, P(VDF-TrFE). It is shown that nanoparticle agglomeration plays a detrimental role and significantly reduces α_ME. Surface functionalization of the nanoparticles by grafting a layer of poly(methyl methacr
