Abstract
We demonstrate resistively detected nuclear magnetic resonance (RDNMR) in a two‐dimensional electron gas (2DEG) formed in single InSb quantum wells. The large g factors of the InSb 2DEG enable construction of the simplest pseudospin quantum Hall ferromagnet (PQHF) characterized by a resistance spike at the filling factor of two using tilted magnetic fields. Dynamic nuclear polarization (DNP) occurs when a large current flows through the PQHF, resulting in the resistance change of the spike. RDNMR signals of high nuclear spin isotopes of In and Sb are clearly observed. Domain structures are believed to be responsible for the DNP process.
