Galvanomagnetic properties of the Cd. .Zn,As. alloy crystals with x= 1.2, t.s and2.4 were measured and discussed in the temperature region from 1.8 to 370K. In thetemperature dependence of the Hall coefficient a maximum was observed at atemperature, around which the resistivity varied approximately as exp (e./kT),for o-Cd...Zn...As. containing - 4x 10" electrons/cm' and p-Cd...Zn...As.containing -3 x 10" holes/cm'. This fxct suggests the presence of two bands withdifferent carrier mobilities. In the latter case, one of the two may be an impurity band.Also, p-Cd...Zn...As. with an intermediate carrier density exhibited a positivemagnetoresistance, A p/pcc T ', at low temperatures, which was explained by means ofthe impurity conduction like that proposed for Ge, Si and other semiconductors.
