      More Details Abstract Fulltext PDF

      Three new phases with compositions, LaSr2FeTiO7, NdSr2FeTiO7 and GdSr2FeTiO7, were prepared by the traditional ceramic method. Lazy–Pulverix analysis of the X-ray diffraction data suggests that the phases crystallize in the RP-type (𝑛 = 2) structure in the space group, 𝐼4/𝑚𝑚𝑚. The cell dimensions along the 𝑐-axis decrease with decrease in size of the rare earth ions. Electrical resistivity, as a function of temperature, shows that the materials are insulators and the resistivity decreases with decrease in the size of the rare earth ion, which is attributed to increase in the three-dimensional character.
