We will report on the anisotropy in (Pb)SnMnTe, studied by ferromagnetic resonance. We have found a cubic anisotropy with a = 73 × 10^{-4} cm^{-1} for Sn_{1-x}Mn_{x}Te and a = 200 × 10^{-4} cm^{-1} for Pb_{0.28-x}Sn_{0.72}Mn_{x}Te. We will indicate some possible explanations for this anomalously large anisotropy.
