We present the application of velocity moment analysis to Mössbauer spectra of single-crystal FeB using synchrotron radiation at BL11XU (SPring-8). This method enables the separation of magnetic dipole and electric quadrupole interactions by analysing first- and second-order velocity moments, independent of nuclear properties. Measurements on FeB single crystals demonstrate the feasibility of this approach, despite challenges from thickness effects.
