Raman Characterization of MBE-Grown Layered MnTe/CdTe Structures

Raman scattering measurements on (MnTe)8 /(Cd 0.64 Ζn 0.30Τc)8 multilayer grown by MBE method and on various (MnTe)n/(CdTe)ι2 multilayers (where n = 8,12,16, 24) were performed at low temperatures.In the z ( x , x ) z p o l a r i z a t i o n , s t r u c t u r e s c o r r e s p o n d i n g t o f o l d e d a c o u s t i c p h o n o n s were found.In z(x, y)z polarization new complex structures were observed in the low-frequency part of Raman scattering spectra.A possible magnetic origin of these structures is discussed.
