Spin waves in single thin films and exchange‐coupled bilayers of f.c.c. MnTe are analyzed theoretically in the low temperature limit. Long‐range antiferromagnetic order of AF‐III type is assumed. The spin‐wave Hamiltonian includes exchange interactions between nearest and next nearest neighbours, magnetic anisotropy and Zeeman term.
