Outline of Final Research Achievements |
We started this project to explore new quantum transport phenomena in chiral p-wave superconducting (Sr2RuO4) junctions using mechanically controllable break junction (MCBJ) technique. However, it turned out to be difficult to perform very-low temperature MCBJ experiments. Thus, we carried out transport characteristics measurements of ferromagnetic ruthenium oxide SrRuO3 (Tc = 160 K) break junctions to investigate an influence of magnetism on local electronic transport. We observed large change of the differential conductance between the ferromagnetic state and the paramagnetic state.
