Abstract :
We have measured the AC QHR using connections which define a closed loop of the device. This allows us to obtain and compare values and field dependencies for both Hall, (R/sub H/), and longitudinal, (R/sub xx/), resistances in the same cool-down. Such measurements allow a more rigorous comparison with DC QHR measurements.
