Abstract

The structure and magnetoelectric properties of flexible PDMS/GFO composites with different GFO weight percentages was studied. The XRD pattern of composites shows the presence of both GFO and PDMS phases. Raman and IR studies confirmed the presence of functional group absorption bands corresponding to PDMS and GFO in the composite system. GFO nanoparticle incorporation is confirmed from fractured micrographs of SEM images. The enhanced thermal stability of the composite material is confirmed through Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) techniques. The field-dependant magnetization data shows a clear hysteresis loop at room temperature, indicating weak ferrimagnetic properties. A significant change in the demagnetization process occurred with the alteration in the filler composition. The frequency-dependent dielectric constant increases with an increase in filler content. Ferroelectric data confirms the room temperature ferroelectricity in the composite samples and polarization increases with filler loading. Room temperature magnetoelectric coupling is confirmed in the samples.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
