Recent quantitative measurements of the orbital to spin magnetic moment ratio $m_L/m_S$ in electron magnetic circular dichroism (EMCD) experiments have given a $m_L/m_S$ ratio that is larger than commonly accepted values. We demonstrate here that plural scattering may noticeably influence the $m_L/m_S$ ratio. An equation is derived which describes its influence as a function of the spectral integrals of the plasmon scattering region and zero-loss peak. The influence of the electron-plasmon scattering can be removed when electron energy-loss spectra of the ionization edge are deconvoluted by the low-loss signal. For a bcc-Fe sample we obtain $m_L/m_S=0.04$ after plasmon removal. We conclude that the plural scattering should be considered when extracting quantitative information from EMCD measurements.
