Invisible magnet cancels its own field, paving the way for denser spintronic devices
DTU researchers engineered a compensated ferrimagnet built from chromium and pyrazine in a metal‑organic network that remains internally magnetized while almost entirely canceling its external magnetic field, even above room temperature. This could reduce stray fields that hinder dense electronics and enable closer integration of spin‑based devices, but the technology is still fundamental research and will require studies of electrical properties and thin‑film integration before real‑world use.
