Abstract
Quantized Hall resistances R(H)(4) and R(H)(2) of a GaAs/AlGaAs hetero structure were compared with reference resistors whose values are clos e to h/4e2 or h/232. The values of the reference resistors were compar ed with a 100 ohm standard resistor via a cryogenic current comparator (CCC) resistance bridge. Results showed that (4 x R(H)(4) - 2 x R(H)( 2))/2 x R(H)(2) = (0.037 +/- 0.019) x 10(-6).
