MegaOhm extraordinary Hall effect in oxidized CoFeB

Research output: Contribution to journalArticlepeer-review


We report on the development of controllably oxidized CoFeB ferromagnetic films demonstrating the extraordinary Hall effect (EHE) resistivity exceeding 1 Ω cm and magnetic field sensitivity up to 106 Ω/T. Such EHE resistivity is four orders of magnitude higher than that previously observed in ferromagnetic materials, while sensitivity is two orders larger than the best of semiconductors.
