Latest Magnetic refrigeration Stories

Luis Hueso, the CICnanoGUNE researcher, together with researchers from the University of Cambridge, among others, has developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened. The work has been published recently in the prestigious journal Nature Materials. Current cooling systems, be they refrigerators, freezers or air conditioning units, make...

Varying magnetic fields and temperature conditions help to elucidate smart materials’ transitory magnetic disorder Novel, smart materials like shape memory alloys very often display so-called glass-like magnetism. Other smart materials with similar properties include those which, when exposed to a magnetic field, change their electrical resistance, known as manganites, or change their temperature, known as magnetocaloric materials. Kaustav Mukherjee and his colleagues from the Consortium...

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...

The work could lead to improved methodologies for creating materials by designScientists have given us a plethora of new materials "“ all created by combining individual elements under varying temperatures and other conditions. But to tweak an intermetallic compound even more, in order to give it the attributes you desire, you have to go deeper and re-arrange individual atoms.It's a process similar to what bioengineers employ when they add and delete genes to create synthetic organisms, and...

British scientists say they are a step closer to making environmentally friendly magnetic refrigerators and air conditioning systems. Imperial College London researchers say magnetic refrigeration technology could provide a green alternative to traditional gas-compression refrigerators and air conditioners, requiring up to 30 percent less energy without the use of ozone-depleting chemicals or producing greenhouse gases. A magnetic refrigeration system works by applying a magnetic field to a...

Scientists are a step closer to making environmentally-friendly 'magnetic' refrigerators and air conditioning systems a reality, thanks to new research published today in Advanced Materials.Magnetic refrigeration technology could provide a 'green' alternative to traditional energy-guzzling gas-compression fridges and air conditioners. They would require 20-30% less energy to run than the best systems currently available, and would not rely on ozone-depleting chemicals or greenhouse gases....

Your refrigerator's humming, electricity-guzzling cooling system could soon be a lot smaller, quieter and more economical thanks to an exotic metal alloy discovered by an international collaboration working at the National Institute of Standards and Technology (NIST)'s Center for Neutron Research (NCNR).*The alloy may prove to be a long-sought material that will permit magnetic cooling instead of the gas-compression systems used for home refrigeration and air conditioning. The magnetic...
