Abstract
The quantized Hall resistance R/sub H/(i), for i=2, 4 and 6 has been measured in the frequency range from DC to 3 kHz by a standard four terminal-pair impedance bridge. For frequencies f, less than 2 kHz, the relative error /spl epsi/(i) between the AC and DC values appeared to be proportional to f and to increase as i decreased. /spl epsi/(6) appeared to be less than 0.4 ppm.<>
