Researchers at the University of Liverpool say they have developed a new material that combines both electrical and magnetic order at room temperature.  

The team from the School of Physical Sciences say they achieved the breakthrough by designed control of the distribution of atoms within the solid state.  

A single material with the distinct properties of magnetization and electrical polarization is difficult to make because the electronic requirements for obtaining them are typically contradictory.  The researchers' approach overcomes material characteristics such as the crystal structure or the atomic composition favoring polarization over magnetization.

The researchers note their work has implications for information storage and processing applications, which cost energy.  They say there is a need for lower-energy approaches due to the rapid growth of the Internet and Internet-enabled devices.  

"We report a new design approach that promises to allow the synthesis and tuning of families of these materials, which are important in the development of low-energy computer memory technologies," says Liverpool professor Matthew Rosseinsky.
