Study of spin-freezing transition in pyrochlore Eu1.9Ce0.1Ti2O7 from AC-susceptibility measurement

In the present investigation, we report structural and magnetic properties of Ce doped (5% at the Eu site) Eu2Ti2O7 (ETO) pyrochlore. From the Rietveld analysis of the x-ray diffraction pattern, prepared samples were found to possess a single-phase cubic structure (Fd-3m). Curie-Weiss (CW) analysis and isothermal magnetization curve imply that anti-ferromagnetic interactions exist in the system AC susceptibility measurements confirm that there is almost no effect on spin freezing with such a small amount of Ce doping.
