Synthesis and characterization of the physical properties of \textit{RE}$_{3}$TiSb$_{5}$ (\textit{RE} $=$ La, Ce)
ORAL
Abstract
\textit{RE}$_{3}$TiSb$_{5}$ (\textit{RE}$=$ La, Ce) is synthesized to investigate the physical properties and test for superconductivity. Ce$_{3}$TiSb$_{5}$ was synthesized using flux growth in both Sn and Zn fluxes while La$_{3}$TiSb$_{5}$ was synthesized using Sn flux. Magnetic, resistive, and heat capacity measurements all indicate that neither of these compounds are superconducting. Based on our results La$_{3}$TiSb$_{5}$ is non-magnetic and Ce$_{3}$TiSb$_{5}$ has an antiferromagnetic phase transition near 5 K. Neither compound exhibits typical metallic transport behavior. This is in contradiction to previous results.
