Longer battery life, more memory in electronics? Rare materials perform at near-room temperature

New research in theoretical physics shows few materials that possess both magnetic properties and controllable temperatures close to room electric polarization.
This discovery could lead to a life of the battery and storage for electronic devices, Yang Yurong said, research assistant professor at the University of Arkansas.
An international team of physicists has its results on 28 May in the journal Nature Communications, an online journal, published by the journal Nature in an article entitled, "Ambient multiferroic materials fence with ferromagnetic properties and electrical adjustable temperature."
A rare class of materials as Multiferroics is known, its electric polarization when under a magnetic field or magnetic properties, when an electric field to change. But often this multiferroic properties as well below ambient temperature so that it's useless for everyday applications.
Accordingly, materials are now used for storage devices, by the force of electricity and magnetism, but not both. ADVERTISING
The research team Yang and Laurent Bellaiche, distinguished professor of physics at the University of Arkansas. Yang, a theoretical physicist, computer models used to make very accurate calculations on a certain class of materials, in order combinations to find the show these properties.

(BD IT TALK) The researchers found that a certain class of multiferroic periodically alternating along a particular direction, which is a superlative must show both magnetic and electric properties of adjustable polarization near room temperature, Yang said.
uperlattice are like a layered cake, where the cake layers are only nanometers thick and are made made from different materials such as multifarious in this work. The next step is the experimental verification of the calculations.

The results were a joint effort with Hong Zhao Jian, a former graduate student visiting the University of Arkansas, which is currently completing his PhD in the department of materials science and engineering at the University receive Zhejiang Hangzhou, China. Also collaborating on the study were Xiang Ming Chen, Zhao Zhejiang University; Wei Ren at the University of Shanghai in China and Jorge Iñiguez at the Institute of Materials Science of Barcelona, ​​Spain.
