A tiny grid pattern has led materials scientists at the National Institute of Standards and Technology (NIST) and the Institute of Solid State Physics in Russia to an unexpected finding about certain electromagnetic nanostructures used in data storage.rnThe team was studying the behavior of nanoscale structures that sandwich thin layers of materials with differing magnetic properties. Such structures have been researched for a few decades because they can have unusual and valuable magnetic properties. The data read heads on modern HDDs usually exploit a version of the giant magnetoresis-tance (GMR) effect, which uses such layered structures.
