X-bit Labs writes researchers from the University of Cambridge have created a new magnetic cooling technology for chips based on the straining of materials. The scientists discovered that by using the straining of materials, and then relaxing it, an effect similar to that of a magnetic field is created, thus inducing the magnetocaloric effect responsible for cooling. The new technology promises to have a lower environmental impact than current cooling system used in refrigerators, freezers and air conditioning units. Full details at X-bit Labs.
The aim of this field of research is to find materials that are efficient, economical and environmentally friendly. So far, 20nm films consisting of lanthanum, calcium, manganese and oxygen have been developed.
“The idea came about at Cambridge University and among various groups in the United Kingdom, France, Ukraine and the Basque Country we have come up with the right material and an effective technique for cooling electronic chips, computer memories and all these types of applications in microelectronics. Technologically, there would not be any obstacle to using them in fridges, freezers, etc. but economically it is not worthwhile because of the size,” stressed Mr. Hueso.
