Measurements have been made on the voltage-current characteristics and resistance transient in $Hg_{1-x}Cd_xTe$ semiconducting alloys having x = 0.20 and 0.22 at 4.2 and 77 K in the absence of a magnetic field, and also in longitudinal and transverse magnetic fields of strength up to 2 kOe. The results confirm that there is a z pinch in the electronhole plasma formed on electrical breakdown in that the magnetic-concentration effect occurs in this plasma in a transverse magnetic field.
