Ferromagnetic quantum phase transition in Sr_1−xCa_xRuO₃ thin films — •Melanie Schneider, Vasile Mosneaga, and Philipp Gegenwart — I. Physikalisches Institut, Georg-August Universität Göttingen,Friedrich-Hund-Platz 1, 37077 Göttingen, Germany

The series Sr_1−xCa_xRuO₃ shows a continuous evolution from itinerant electron ferromagnetism with T_C ≈ 160 K (x = 0) towards a paramagnetic metallic state at x = 1. For thin films, which have been grown epitaxially on SrTiO₃ and NdGaO₃ substrates by metalorganic aerosol deposition technique, we present electrical transport measurements extended to mK temperatures and in applied magnetic fields. We also investigated nonlinear transport at high current densities in the non-Fermi liquid regime for microstructured thin films. Work supported by DFG through SFB 602, TP A19."
