Magnetic phase diagram of multiferroic Eu1−xLuxMnO3 investigated by infrared spectroscopy
چکیده انگلیسی

This work reports on the temperature dependence of the infrared reflectivity of multiferroic Eu1−xLuxMnO3, with 0 ≤ x ≤ 0.3. The semi-quantum model of dielectric function is used in order to extract the effective complex optical conductivity from the power reflectivity spectra. The analysis of the temperature dependence of very general global spectroscopic functions allows the observation of subtle modifications that stem from the stabilization of different magnetic phases. The phase diagram inferred from the spectroscopic data is presented and compared with that previously reported for the mixed system.
