MAGNETOPHONON RESONANCES WITH SIMULTANEOUS EMISSION ABSORPTION OF PHONONS IN ZNXCDYHG1-X-YTE

The influence of temperature on oscillations oi the transverse magneto resistance of ZnxCdyHg1-x-yTe (x = 0.08, y = 0.11) in the range 77-200 K and under magnetic fields up to 2.5 T has been studied. It has been shown that the structure of observed oscillations cannot be interpret ed by participation of one kind of phonons only in magnetophonon reson ance, We observed series ''a''-LO(ZnTe), ''b''-LO(CdTe), ''c''-LO(HgTe ), ''d''-Lo(ZnTe)-LO(HgTe), and ''e''-LO(CdTe)-LO(HgTe). An interpreta tion of experimental peaks with the help of magnetophonon resonances a t differences of phonon frequencies describing the different solid sol ution sublattices (HgTe-like, CdTe-like, and ZnTe-like) is given.
