Advanced Optical Materials, EarlyView.This work demonstrates fast electrical control of the phase of broadband terahertz pulses using a field‐free spintronic emitter. An antenna‐integrated Ta/CoFeB/Pt heterostructure switches its magnetization through spin‐orbit torque with 1 μs$\umu{\rm s}$ electrical pulses, producing complete π$\pi$‐phase inversion without external magnetic fields ...
