Fundamental step toward ultrafast magnetism-based computers comes from multi-institution team involving UCLA Science + Technology Fundamental step toward ultrafast magnetism-based computers comes from multi-institution team involving UCLA Key takeaways. If computers used ripples in magnetic fields, called magnons, to encode and process information, the result would be devices with potential memory speed on the order of billionths of a second. UCLA researchers and partners caused two distinct types of magnons to interact so that output is not directly proportional to input - a crucial step toward computing advances. This multi-institution, long-term research collaboration is studying magnons using a rarely used but promising terahertz laser technology. One vision for the future of computing involves using ripples in magnetic fields - called magnons - as a basic mechanism. In this application, magnons would be comparable to electricity as the basis for electronics.
