Abstract

We report a systematic study on the effect of partial substitution of Sc $^{3+}$ by Ti $^{4+}$ in Sr $_{2}$ ScFeAsO $_{3}$ , Ca $_{2}$ ScFeAsO $_{3}$ and Sr $_{3}$ Sc $_{2}$ Fe $_{2}$ As $_{2}$ O $_{5}$ on their electrical properties. High level of doping results in an increased carrier concentration and leads to the appearance of superconductivity with the onset of T $_{c}$ up to 45 K.
