Major Applications of Advanced Nano Multiferroic Magneto-Electric Materials in Devices: Synthesis and Characterization

Abstract

This paper discusses the literature review on various aspects of ferromagnetic and ferroelectric materials and their composites. Due to the technical significance of linking individual components of these multiferroic composites, the inquiry has been given much emphasis. These materials are known as direct magneto-electric coupling and are capable of electrically tuning magnetization or vice-versa. In the current case, the multiferroic field shifted more towards the application portion than its simple physics. ‘These goals take into account the invention of innovative nanoscale materials with efficient electrical and magnetic binding at room temperature0.0. A forum for potential developments can be provided by multiferroic with strong room temperature magnto-electric (ME) coupling. The properties of PbTiO3-Ni0.5Co0.5Fe2O4 composites and their ball-milled samples have been addressed. XRD and SEM micrographs also verified the phase formation and grain size of composites. For milled samples, the average grain size was less than 100 nm. The pristine composite (PT-NCF) XRD pattern exhibits increased peak strength corresponding to the PT period. It is found that with milling length, the amplitude of XRD peaks decreases and peak width increases. A wide difference in transition temperature, Tc, was reported during dielectric measurements due to the reduction in grain size and existence of the ferromagnetic phase. In addition, for the higher milling period study, the lower Tc value is registered. At room temperature, the P-E loops of all the composites of varying particle sizes appeared to be lossy in design. In comparison, as the grain size reduces, the region of the P-E loop rises. In comparison with the ferroelectric (PT) stage, the percentage of the ferromagnetic (NCF) step is weak, but the magnetization values obtained for all the composites were still significantly strong. In this post, recent developments in multiferroic magntoelectric nanostructures clarify.
