Common rust’s rare magnetism could power ultrafast quantum devices

by
The Blueprint

Scientists in the US have discovered that hematite features a rare new form of magnetism, which reportedly paves the way for spintronics technology that could transform data processing and storage. The discovery, made by researchers at Oak Ridge National Laboratory (ORNL), provided one of the clearest experimental evidence of alternating magnetism, a newly confirmed third … Read more
