Abstract
A major challenge in spintronics is reducing power consumption due to magnetization switching in ferromagnets. Here researchers demonstrate a scheme of orbital-controlled magnetization switching using a ferromagnetic oxide interface. Deterministic, magnetic-field-free 90\ifmmode^\circ\else\textdegree\fi{} magnetization switching is achieved solely by applying an extremely small electric field, and the associated current density is reduced by 8 orders of magnitude, compared to current-driven switching. These results form a basis for a universal strategy for highly efficient magnetization control by band engineering.
