摘要：

Quantum phase modulation is achieved in a metallic nanoring with a FeNi/Cu/FeNi (ferromagnet/normal-metal/ferromagnet) layer. Both frequency and amplitude of Aharonov-Bohm oscillation are found to be modified with respect to the magnetization configurations, indicating that the phase modulation originates from the spin-orbit scattering induced by the magnetization of the ferromagnets. Such phase modulation is "crossover" phenomena between mesoscopic magnetism and microscopic quantum interference effects, which provides fundamental knowledge upon quantum spin transport.
