The propagation of magnetoplasma waves in the configuration B ‖ C 2 ‖ k is measured for a number of n‐type semiconducting Bi 1– x Sb x alloys (0.07 < x < 0.14) at frequencies of 41 and 70 GHz and helium temperatures. The attenuation behaviour and a comparison between the experimental and the theoretical dispersion of the waves yield a rapid increase of the maximum cyclotron mass m 1 c with increasing x , which by far exceeds the variation of the low cyclotron mass m 2 c . Under the given conditions, the results obtained are largely independent of the dispersion relation of the electrons, which is used in the description of the wave dispersion in a quantizing magnetic field.
