The magnetophonon effect observed in the Hall coefficient

Abstract

Magnetophonon extrema are reported for the first time in the Hall coefficient. With weak electric fields and high lattice temperatures, minima are found at the resonant fields with n-type InSb and InAS but maxima are found at these fields with n-type GaAs. Under hot electron conditions at low lattice temperatures, magnetophonon peaks are also observed in the all coefficient with GaAs.
