We report a resistively detected nuclear magnetic resonance (RDNMR) measurement in a GaAs-based quantum point contact in the quantum Hall breakdown regime. We focus on the detection of the $^{75}\mathrm{As}$ RDNMR signal at different perpendicular ma

The even-denominator states have attracted considerable attention owing to their possible applications in future quantum technologies. In this letter, we first report a 3/2 diagonal resistance, indicating the existence of a 3/2 state in a nanometer-s

Here we show RD-NMR signal dependency on magnetic field in a GaAs based quantum point contact (QPC) in quantum Hall breakdown regime. For this purposes we employ triple gate QPC to control the confinement of 2DEG and locally generate nuclear spin pol

We demonstrate a way to polarize and detect nuclear spin in a gate-defined quantum point contact operating at high Landau levels. Resistively-detected Nuclear Magnetic Resonance (RDNMR) can be achieved up to the $5$th Landau level and at a magnetic f
