N2 - An all-electrical spin resonance effect in a GaAs few-electron double quantum dot is investigatedexperimentally and theoretically. The magnetic field dependence and absence of associated Rabioscillations are consistent with a novel hyperfine mechanism. The resonant frequency is sensitive tothe instantaneous hyperfine effective field, and the effect can be used to detect and create sizable nuclear polarizations. A device incorporating a micromagnet exhibits a magnetic field difference between dots, allowing electrons in either dot to be addressed selectively.
