Show more >We report on the fabrication of an organic multiferroic tunnel junction (OMFTJ) based on an organic barrier of the Poly(vinylidene fluoride) (PVDF):Fe3O4 nanocomposite. By adding Fe3O4 nanoparticles into the PVDF barrier, we found that the ferroelectric properties of the OMFTJ are considerably improved compared to those with a pure PVDF barrier. This can lead to tunneling electroresistances of about 450% at 10 K and 100% at room temperature (RT), which are much higher than those of the pure PVDF based device (70% at 10 K and 7% at RT). OMFTJs based on the PVDF:Fe3O4 nanocomposite could open new functionalities in smart multiferroic devices via the interplay of the magnetism of nanoparticles with the ferroelectricity of the organic barrier.Show less >
