New devices could reduce excess heat in computers

Science Daily  September 13, 2018 An international team of researchers (Germany, Norway, the Netherlands) demonstrated that antiferromagnetic iron oxide, which is the main component of rust, is a cheap and promising material to transport information with low excess heating at increased speeds. They used platinum wires on top of the insulating iron oxide to allow an electric current to pass close by. This electric current leads to a transfer of energy from the platinum into the iron oxide, thereby creating magnons. Antiferromagnets are unaffected by external magnetic fields, which is a key requirement for future data storage. Antiferromagnet-based devices can […]
