Abstract :
Summary form only given, as follows.Accurate comparisons have been made at 1.6 kHz of the quantized Hall resistances corresponding to different samples, different values of the quantum number i (i=2 and i=4), and to both directions of the magnetic flux density applied to the samples. Preliminary results indicate that the different quantized resistances are consistent to within /spl plusmn/1 part in 10/sup 7/.
