Efforts have been made to control the spin-relaxation rate, the Curie temperature, or the magnetic anisotropy with a gate voltage, but these effects are usually small and volatile. We used ferroelectric tunnel junctions with ferromagnetic electrodes to demonstrate local, large, and nonvolatile control of carrier spin polarization by electrically switching ferroelectric polarization. Our results represent a giant type of interfacial magnetoelectric coupling and suggest a low-power approach for spin-based information control.

We utilize resonant magnetic reflectivity of circularly polarized synchrotron radiation which allows us to distinguish unambiguously the local magnetism on carbon from that on Fe through individual core-level excitations. Clear magnetic signals of carbon are obtained by exploiting the standing-wave technique.
