A team of Canadian-Bulgarian researchers has developed a promising novel approach for magnetic cooling that's far more efficient and "greener" than today's standard fluid-compression form of refrigeration. WASHINGTON, June 10, 2014 /PRNewswire-USNewswire/ -- Magnetic cooling is a promising new refrigeration technology boasting several advantages - ranging from lower energy consumption to eliminating the use of hazardous fluids - that combine to make it a much more environmentally...

Like turning coal to diamond, adding pressure to an electrical material enhances its properties. Now, University of Illinois at Urbana-Champaign researchers have devised a method of making ferroelectric thin films with twice the strain, resulting in exceptional performance. Led by Lane Martin, a professor of materials science and engineering, the group published its results in the journal Advanced Materials. Ferroelectric materials, metal oxides with special polarization properties, are...

Although scientists have been aware that magnetism and electricity are two sides of the same proverbial coin for almost 150 years, researchers are still trying to find new ways to use a material´s electric behavior to influence its magnetic behavior, or vice versa. Thanks to new research by an international team of researchers led by the U.S. Department of Energy´s Argonne National Laboratory, physicists have developed new methods for controlling magnetic order in a particular...

ORNL experiments prove nanoscale metallic conductivity in ferroelectrics The prospect of electronics at the nanoscale may be even more promising with the first observation of metallic conductance in ferroelectric nanodomains by researchers at Oak Ridge National Laboratory. Ferroelectric materials, which switch their polarization with the application of an electric field, have long been used in devices such as ultrasound machines and sensors. Now, discoveries about ferroelectrics'...

Dr. Ariando of the National University of Singapore discovered a collective electronic state not seen before in the bulk of either 2 individual insulating oxides, thus demonstrating that electrons at their interface can now exhibit ferromagnetism In many ionic materials, including the oxides, surfaces created along specific directions can become electrically charged. By the same token, such electronic charging, or 'polarization', can also occur at the interface of two connecting materials....

For the first time, engineering researchers have been able to watch in real time the nanoscale process of a ferroelectric memory bit switching between the 0 and 1 states. Ferroelectric materials have the potential to replace current memory designs, offering greater storage capacity than magnetic hard drives and faster write speed and longer lifetimes than flash memory. Replacing dynamic random access memory–the short-term memory that allows your computer to operate–with...

Nature Materials: new multiferroic material developed An international team of researchers from France and Germany has developed a new material which is the first to react magnetically to electrical fields at room temperature. Previously this was only at all possible at extremely low and unpractical temperatures. Electric fields are technically much easier and cheaper to produce than magnetic fields for which you need power guzzling coils. The researchers have now found a way to control...

HZB scientists observe how a material at room temperature exhibits a unique property — a 'multiferroic' material with potential uses for cheap and quick data storage. Researchers at Helmholtz-Zentrum Berlin (HZB) in close collaboration with colleagues in France and UK, have engineered a material that exhibits a rare and versatile trait in magnetism at room temperature. It´s called a “multiferroic,” and it means that the material has properties allowing it to be both...

By combining two frontier technologies, spintronics and straintronics, a team of researchers from Virginia Commonwealth University has devised perhaps the world's most miserly integrated circuit. Their proposed design runs on so little energy that batteries are not even necessary; it could run merely by tapping the ambient energy from the environment. Rather than the traditional charge-based electronic switches that encode the basic 0s and 1s of computer lingo, spintronics harnesses the...

New multiferroic mechanism could lead to next-generation memory and sensing devices Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have observed a new way that magnetic and electric properties "” which have a long history of ignoring and counteracting each other "” can coexist in a special class of metals. These materials, known as multiferroics, could serve as the basis for the next generation of faster and energy-efficient logic, memory, and...
