The FMR spectra of the La0.67Ca0.33MnO3 ferromagnetic film deposited onto y-cut LiNbO3 substrate have been investigated in wide range of temperature below the Curie point(250K). The strain was mechanically introduced into film using a special holder configuration. The effect of this action results in a shift of resonance field with respect to unstressed state. The reduced change of in-plain resonance field (Δ Hs|), which is proportional to magnetoelastic stress parameter Bγ ,2 fits well Callen theory corresponding to single ion crystal field interaction in the sample in a whole ferromagnetic range of temperatures.
