Magnetically tunable DC electrical properties of LSMO-PVDF magnetoelectric composite flexible film

The current era sees a surge in research interest surrounding multiferroic magnetoelectric composite flexible films, driven by their multifunctionality in creating wearable electronic devices. Aligned with this interest, our endeavors are aligned with this pursuit, leading us to develop an inorganic-organic magnetoelectric flexible composite film. This was achieved through a low-temperature chemical pyrophoric reaction process, followed by a solution casting technique. In this context, we have prepared “0.5La_0.7Sr_0.3MnO₃ − 0.5Polyvinylidene Fluoride” multiferroic nanocomposite flexible film, having a weighted ratio of 50:50. Further, we have investigated the Current-Voltage characteristics of the composite with the variation of applied DC magnetic field at room temperature. Moreover, due to the applied magnetic field, we have calculated the change in current at any constant voltage. The composite film demonstrates a notable alteration in electrical properties when subjected to an applied magnetic field. While the observed effect may not be sufficiently efficient for the fabrication of electronic devices at its current level, our ongoing efforts in the field are dedicated to enhancing this change in current under the influence of the applied magnetic field.
