Detection of spin waves with higher wave vector values is now possible with spin-polarized electron energy loss spectroscopy (SPEELS), a method recently reported to have been applied for detecting spin waves in a range of wave vector values covering in principle the whole Brillouin zone. This paper presents a comparison of spin-wave spectra resulting from our theoretical investigations (within the model based on a bi-linear Hamiltonian expressed in second-quantization formalism) with the corresponding SPEELS results obtained recently for 5 ML Fe film deposited on W(110) [JMMM, 272-276, 2126 (2004)]. By considering the mixed bcc-fcc film structure we were able to explain the details of the reported SPEELS spectra, indicating the surface character of the modes associated with the observed peaks.
