متن کاملThe Effects of Multiphase Formation on Strain Relaxation and Magnetization in Multiferroic BiFeO3 Thin Films
Multiferroic materials simultaneously display ferroelectric and ferromagnetic properties in the same phase. [1] In the 1960s to 1970s, these materials were first investigated to understand the magnetoelectric (ME) coupling effect. Recently, there is increased interest in multiferroic materials because of their potential applications in novel devices using the magnetoelectric effects including s...
متن کاملNanoscale Domain Control in Multiferroic BiFeO3 Thin Films
With an ever-expanding demand for data storage, transducers, and microelectromechanical (MEMS) systems applications, materials with superior ferroelectric and piezoelectric responses are of great interest. The lead zirconate titanate (PZT) family of materials has served as the cornerstone for such applications up until now. A critical drawback of this material, however, is the presence of lead ...
متن کاملPolar-Graded Multiferroic SrMnO3 Thin Films.
Engineering defects and strains in oxides provides a promising route for the quest of thin film materials with coexisting ferroic orders, multiferroics, with efficient magnetoelectric coupling at room temperature. Precise control of the strain gradient would enable custom tailoring of the multiferroic properties but presently remains challenging. Here we explore the existence of a polar-graded ...
متن کاملSingle-domain multiferroic BiFeO3 films
The strong coupling between antiferromagnetism and ferroelectricity at room temperature found in BiFeO3 generates high expectations for the design and development of technological devices with novel functionalities. However, the multi-domain nature of the material tends to nullify the properties of interest and complicates the thorough understanding of the mechanisms that are responsible for th...
