Description
Manoj Kumar Rout and Sunita Keshri build light sensors whose response can be tuned with a magnet. The devices stack thin films of cobalt-zinc ferrite on silicon, topped with a transparent conducting layer. One version adds dysprosium, a rare-earth element, into the ferrite. The 2026 team sputtered the films, checked their structure and magnetism, and measured how the devices answer broad light, spanning 300 to 1100 nanometres, under a small applied voltage.
The dysprosium version delivered nearly three times the photocurrent of the plain one, switched faster, and scored higher on sensitivity measures. A magnetic field up to 3000 oersted boosted the current further in both devices, apparently by lining up charge carriers and cutting losses. Some photocurrent even lingered after the field was removed. The authors see promise for sensors whose light response can be dialled magnetically, with uses in optical sensing and spin-based electronics.
