Article Journal of Physics: Condensed Matter 0953-89841361-648X 27 27 275801– quantum Hall effect; resistively detected nuclear magnetic resonance (RDNMR); electronic domains; electronic spin polarization The resistively detected nuclear magnetic resonance (RDNMR) performed on a two-dimensional electron gas is known to exhibit a peculiar 'dispersive' line shape at some filling factors, especially around $\nu =1$ . Here, we study in detail the inversion of the dispersive line shape as a function of the filling factor from $\nu =1$ to $2/3$ . The RDNMR spectra show a new characteristic W line shape in the longitudinal resistance, whereas dispersive lines detected in the Hall resistance remain unchanged. This W resonance, like the dispersive line, can be fitted correctly by a model of two independent response functions, which are the signatures of polarized and unpolarized electronic sub-systems. 2015-07-15 IOP Publishing English Information and Communication Technologies; National Research Council Canada Yes 23001712 Export as RIS Report a correction 4275801d-e5b7-4f68-8a4a-72008d603639 2017-03-21 2017-03-21
