Room-temperature measurements of Faraday rotation, magneto-thermoelectric power, and infrared reflectance have been made on homogeneous coarsely polycrystalline n-type samples of GaxIn1-xSb alloys produced by the horizontal Bridgman technique. Using these data and a Kane equation for the 000 conduction band, values of the bottom of the band effective mass have been determined over the composition range 0 X 0.85. The results from the three different techniques show very good agreement. From the data, values are obtained also for the square of the matrix element P superscript 2, the high-frequency dielectric constant epsilon sub infinity symbol and the scattering parameter s for the various alloy specimens.
