Multiferroics may speed memory, sensing devices

摘要

A team of researchers from the U.S. Dept. of Energy's Brookhaven National Laboratory has discovered a new way that magnetic and electric properties can coexist in a special category of metals. These materials, known as multiferroics - magnetic materials with north and south poles that can be reversed with an electric field - promise to enable faster and energy-efficienct logic, memory, and sensing technology. This team together with colleagues from the Leibniz Institute for Solid State and Materials Research in Germany, published their findings in the July 25, 2011, edition of Physical Review Letters.
