• This paper reports magnetic quantum oscillations of high electric field mag-netoresistance due to nonradiative carrier recombination processes, i.e., Auger pro-cess and Shockley-Read process, in n-Hg. .Cd,Te (MCT) (,v:0.2). A new effect ofmagnetic quantum oscillation due to the electron trapping with emission of multipleLO-phonons associated with Shockley-Read process was observed together with theoscillation due to Auger process. Oscillations were observed successfully in a widetemperature range 4.2 - 100 K, by the combination of a pulse technique and a secondderivative method. The dominant origins of the oscillation can be clearly determinedfrom the temperature dependence of the peak positions. In typical samples of MCT,Shockley-Read process governs the recombination at the lower temperature andAuger process at the higher temperature in the magnetic field. The temperatures ofthe crossing over of the two processes were determined for several samples withdifferent carrier concentrations n and different electron mobilities q.(n=3Xl0"- 2 X 10" cm ', jt.= 8 X 10' - 2 X 10' cm'/ V-s at 4.2 K).
