Researchers develop a magnetic cooling system close to absolute zero

A team of researchers has developed a magnetic cooling system that allows reaching temperatures close to absolute zero.

Researchers at Kiutra, a subsidiary of the Technical University of Munich, have developed the first commercial magnetic cooling system that allows you to approach absolute zero (-273.15ºC). One of the most interesting aspects of this system is that it can cool based on a magnetic technology system. It can maintain extreme permanent cooling. Something very interesting is that it does not require strange and expensive liquid gases, such as the helium-3 isotope to work.

This team of researchers highlights that these temperatures close to absolute zero are used in various fields of research. They have highlighted that it is important for quantum physics and for the development of technologies based on quantum mechanics. This solution will allow technologies for quantum physics to go out of the laboratories to the market.

Not that magnetic refrigeration systems are new, since in theory they have been around for years. The team consisting of Alexander Regnat, Jan Spallek, Tomek Schulz and Prof. Christian Pfleiderer. They have highlighted that previous solutions presented challenges and limited durability over time. This prevented its widespread use.

Regnat has highlighted about this: "We are the first commercial supplier in the world of a cooling system that can magnetically reach temperatures close to absolute zero (close to -273 ° C) permanently". “Our big advantage is that we don't need expensive helium-3. All we need is electricity,” adds Regnat.

An important advance to improve refrigeration systems at an industrial and technical level. Obviously this cooling system is expensive and complex and is not intended for computer hardware. Although it is possible that with research and development something viable will be reached, technically. Having a cooled processor at extremely cold temperatures should allow for a lot of overclocking. Maybe one of these would have been great for AMD's Radeon VII.
