Description
We have revealed the relationship between the orbital ordering and the magnetism in the perovskite Ti oxides RTiO3 (R; rare earth elements) by using resonant X-ray scattering (RXS) near the K absorption edge of Ti. We observed the temperature dependence of the resonant signal in SmTiO3. The resonant signal hardly changed at the magnetic phase transition. Besides, the energy spectra at Q=(003) and the full width at half maximum (FWHM) for the 2θ-ω scan are unchanged. Combining with the behavior that the periodicities of the azimuthal angle dependence for GdTiO3 and SmTiO3 are identical at each scattering vector, it is concluded that the change of the magnetism from ferromagnetic (FM) to antiferromagnetic (AFM) has little effect on the orbital ordering in RTiO3
