Magnet with near-zero external field could reshape future electronics

Phys · · 656 words · By Technical University

An international research team developed a new magnetic material, a compensated ferrimagnet, that maintains a stable internal magnetic structure with almost no external field above room temperature. This material is significant for spintronics, a field that uses electron spin to process information, because its weak external field minimizes interference in electronic circuits. The research is considered fundamental, with future work planned to test its integration into actual electronic components.
