Abstract

We find spin-dependent enhancement/suppression of scattering between fractional quantum Hall (FQH) edge channels (ECs), which originates from the hyperfine interaction between electron spins and nuclear spins. Nuclear magnetic resonance is detected via the FQH-EC transport, indicating the relevance of dynamic nuclear polarization (DNP). Spin polarizations of FQH ECs are inferred from the DNP.
