Energy-domain57Fe polarization-dependent synchrotron radiation Mössbauer spectroscopy was developed by using a diamond X-ray phase plate and an iron borate nuclear Bragg monochromator. The former controls the polarization of the incident synchrotron radiation X-rays and the latter filters the57Fe-Mössbauer radiation with a narrow bandwidth of ∼3.4 Γ0(Γ0≃ 4.7 neV: natural linewidth of the57Fe nucleus) from the broadband synchrotron radiation. The developed nuclear diffraction optics allowed57Fe-Mössbauer studies to be performed with various polarization states,i.e.linear polarization, circular polarization and non-polarization. In this paper, the spectrometer system, beam characterization, performance-test experiments and a grazing-incidence Mössbauer measurement of an isotope-enriched (57Fe: 95%) iron thin film are described.
