Advances in Multiferroic Nanomaterials Assembled with Clusters

Abstract

As an entirely new perspective of multifunctional materials, multiferroics have attracted a great deal of attention. With the rapidly developing micro- and nano-electro-mechanical system (MEMS&NEMS), the new kinds of micro- and nanodevices and functionalities aroused extensive research activity in the area of multiferroics. As an ideal building block to assemble the nanostructure, cluster exhibits particular physical properties related to the cluster size at nanoscale, which is efficient in controlling the multiferroic properties for nanomaterials. This review focuses on our recent advances in multiferroic nanomaterials assembled with clusters. In particular, the single phase multiferroic films and compound heterostructured multiferroic films assembled with clusters were introduced detailedly. This technique presents a new and efficient method to produce the nanostructured multiferroic materials for their potential application in NEMS devices.

Synthesis, Characterization, and Optimization of Magnetoelectric BaTiO3–Iron Oxide Core–Shell Nanoparticles

“…Nanomaterials 2020, 10, x FOR PEER REVIEW 7 of 10 agreed well with the maghemite stoichiometry. Small FWHM of peaks (1)(2)(3)(4) supported the presence of ϒ-Fe2O3 phase in CSNP structures. All peaks were deconvoluted using the Gaussian parameters.…”

“…Coupling between electric and magnetic properties (e.g., magnetic polarization from electric field and vice versa) is essential for several technologies. Application of the magnetoelectric (ME) effect-based devices would include but not limited to micro-and nanoelectromechanical systems (MEMS and NEMS), data storage media, spintronics, spin valves, nonvolatile random access memories, and so on [4][5][6]. Unlike compound multiferroic materials, which is a mixture of materials without an interface, the composite structure with ferroelectric and magnetic interfaces typically yields an excellent ME coupling response.…”
