Controlling the electronic and magnetic properties by Sn substitution in SrRuO₃ epitaxial films

Controlling the lattice strain in films through chemical substitution has been widely investigated in strongly correlated electronic systems as a means to change electronic and magnetic properties from those of the bulk. Here we present a systematic study on epitaxial SrRu_1−xSn_xO₃ (0 ≤ x ≤ 1) thin films grown by pulsed laser deposition to achieve stable phases in this family of quaternary perovskites, which has been unstable in bulk. We find a gradual expansion of the c-axis lattice parameter with Sn doping, serving as a means to tune chemical pressure and magnetism. This talk will focus on the electronic, magnetic, and magnetotransport properties by the effects of Sn doping in SrRuO₃ thin films.
