Temperature dependence of the magnon frequency was studied for cubic MnTe epilayers by the Raman scattering measurements. Experimental data are compared to the results of theoretical calculations performed within the framework of the Heisenberg model using Green's function formalism.
Raman scattering measurements on (MnTe)_{8}/(Cd_{0.64}Zn_{0.36}Te)_{8} multilayer grown by MBE method and on various (MnTe)_{n}/(CdTe)_{12} multilayers (where n=8,12,16,24) were performed at low temperatures. In the z̅(x,x)z polarization, structures corresponding to folded acoustic phonons were found. In z̅(x,y)z polarization new complex structures were observed in the low-frequency part of Raman...
