Abstract
Raman scattering measurements on (MnTe)(8)/(Cd0.64Zn0.36Te)(8) multila yer grown by MBE method and on various (MnTe)(n)/(CdTe)(12) multilayer s (where n = 8, 12, 16, 24) were performed at low temperatures. In the (z) over bar(x,x)z polarization, structures corresponding to folded a coustic phonons were found. In (z) over bar(x,y)z polarization new com plex structures were observed in the low-frequency part of Raman scatt ering spectra. A possible magnetic origin of these structures is discu ssed.
