摘要：

We report the resistively-detected nuclear magnetic resonance (RDNMR) study for a quantum wire (QW) made of the two-dimensional electron gas in the quantum Hall (QH) regime. The lineshapes of RDNMR vary as the radio-frequency power and the bias voltage. We found that the observed peculiar lineshapes similar to those known as the 'dispersive' ones emerge near Landau level filling nu similar to 1 QH regime.
