(a) Experimental setup for the resistively detected NMR. The specimen is mounted on a plastic chip carrier. An 8-turn coil (red colored) around the sample is used to couple RF radiations to the specimen. A red LED is used for low temperature illumination. (b) shows R_xx and R_xy as a function of RF frequency from 10.60 to 10.75 MHz. Resonant behavior is observed in both R_xx and R_xy at ~10.69 MHz. The blue, red, and green dots indicate the chosen frequencies under which the I-V measurements are performed, as shown in Fig. 3.
