摘要：

Magnetophonon oscillations have been observed in the alloy system InAs 1-xPx. Two magnetophonon series were detected across the complete range of alloy compositions, resulting from the two LO phonon modes present in mixed crystals of InAs1-xPx. The fundamental fields have been used to calculate the LO phonon energies and to determine the temperature dependence of the effective mass. Magnetophonon oscillations were also observed in the Hall coefficient and these exhibited phaseshifts and reversals of sign with respect to the extrema observed in the transverse magnetoresistance.
