Abstract

The magneto-opticol effect was investigated for the cholcopyrite compound 
ZnGeP2 ,the change in the energy gap due to the magnetic field was measured
to be =~ 0.002 eV at room temperature. The temperature coefficient of 
AEg.B(T)was found to be 1.67 X10-4 eV/K in lhe temperature range(300-400)K. 
the reduced effective mass of carriers m* wos calculated and it found to 
decrease with increasing temperature.

Keywords: ZnGeP2,Magneto-optical effect, Semiconductor compounds, Optical properties.
