Combined electron resonance driven by an all-oscillating potential of patterned magnets.
A novel mechanism is proposed for the phenomenon of combined electron resonance. It is shown that the spatially localized microwave fields of an Fe stripe array mediate the intense electronic transitions involving the changes in both spin and orbital quantum numbers when the electron moves along a cyclotron orbit in a semiconductor (e.g., InGaAs-based) quantum well. This discovery bridges the fields of spintronics and quantum computing, paving the way for conceptually new hybrid devices based on ferromagnetic and semiconductor structured materials.
