Influence of doping on the physical properties of Ca$_{10-x}$RE$_x$Pt$_3$As$_8$(Fe$_{2-y}$Pt$_y$As$_2$)$_5$

Ca$_{10-x}$RE$_x$Pt$_3$As$_8$(Fe$_{2-y}$Pt$_y$As$_2$)$_5$ is a new FeAs-based superconductor. We report the change of its superconducting transition temperature $T_c$ and physical properties upon chemical doping in either Ca (using La or Gd) or Fe (using Pt) site. While partial replacement of Fe by Pt results in $T_c$ up to $21 K$, we find that the substitution of Ca by La is most effective pushing $T_c$ to 30 K. The doping in both sites reduces the in-plane resistivity and anisotropy. The doping dependance of electrical transport properties will be presented and discussed.
