Design Strategy and Prediction of New Room Temperature Magnetoelectric Multiferroics

چکیده
Perovskite ABO3 oxides display many promising functional properties including ferroelectricity and magnetism. An ongoing challenge has been to design and synthesize materials in which ferroelectric and magnetic orderings not only coexist in a single phase above room temperature, but also are nontrivially coupled. Such a cross coupling between these different ferroic orderings could lead to many novel applications, in particular, involving electrical control of magnetism that is required in case of MERAMs or magnetic capacitors.

متن کاملMagnetic switching of ferroelectric domains at room temperature in multiferroic PZTFT
Single-phase magnetoelectric multiferroics are ferroelectric materials that display some form of magnetism. In addition, magnetic and ferroelectric order parameters are not independent of one another. Thus, the application of either an electric or magnetic field simultaneously alters both the electrical dipole configuration and the magnetic state of the material. The technological possibilities...
متن کاملRoom temperature multiferroicity in Bi4.2K0.8Fe2O9+δ
Magnetoelectric multiferroics are materials that have coupled magnetic and electric dipole orders, which can bring novel physical phenomena and offer possibilities for new device functions. In this report, single-crystalline Bi(4.2)K(0.8)Fe(2)O(9+δ) nanobelts which are isostructural with the high-temperature superconductor Bi(2)Sr(2)CaCu(2)O(8+δ) are successfully grown by a hydrothermal method....
متن کاملElectric control of magnetism at room temperature
In the single-phase multiferroics, the coupling between electric polarization (P) and magnetization (M) would enable the magnetoelectric (ME) effect, namely M induced and modulated by E, and conversely P by H. Especially, the manipulation of magnetization by an electric field at room-temperature is of great importance in technological applications, such as new information storage technology, fo...
متن کاملAn organic approach for nanostructured multiferroics.
Multiferroics are materials that simultaneously exhibit more than one ferroic order parameters, such as ferroelectricity, ferroelasticity and ferromagnetism. Recently, multiferroicity has received a significant revival of interest due to the colossal magnetoelectric coupling effect for the development of nano-ferronics. In this mini-review, we focus on a recent study of ferroelectricity, magnet...
