We have studied fundamental properties of weak-link Sr2RuO4/Sr2RuO4 Josephson junctions fabricated by making a narrow constriction on superconducting Sr2RuO4 films through laser micro-patterning. The junctions show a typical overdamped behavior with much higher critical current density, compared with those previously reported for bulk Sr2RuO4/s-wave superconductor junctions. Observed magnetic field and temperature dependences of the Josephson critical current suggest that the chiral p-wave is…

A Review of Electronic Transport in Superconducting Sr2RuO4 Junctions

We review electronic transport in superconducting junctions with Sr2RuO4. Transport measurements provide evidence for chiral domain walls and, therefore, chiral superconductivity in superconducting

Superconductivity in Uniquely Strained RuO_{2} Films.

The findings indicate that simple transition metal oxides such as those with a rutile structure may be suitable for further exploring superconductivity by controlling phonon modes through the epitaxial strain.



Josephson Effect in Junctions of Sr2RuO4

Josephson effect between two Sr 2 RuO 4 (SRO) is theoretically studied based on a new formula of Josephson current. We analytically calculate the Josephson current in clean SRO/insulator/SRO

Growth of superconducting Sr2RuO4 thin films

Sr2RuO4 is a superconductor with a low transition temperature (Tc∼1 K), but has a unique character of p-wave symmetry of the order parameter, demanding epitaxial thin films for Josephson junction

We report the growth of superconducting Sr2RuO4 films by oxide molecular beam epitaxy (MBE). Careful tuning of the Ru flux with an electron beam evaporator enables us to optimize growth conditions

Direct observation of the superconducting gap of Sr2RuO4

We report the direct observation of the superconducting gap of Sr 2 RuO 4 , by means of tunnelling spectroscopy. The tunneling conductance parallel to the c axis was measured using a scanning

High-Supercurrent-Density Contacts and Josephson Effect of Strontium Ruthenate

We have developed a process of fabricating high-supercurrent-density contacts to Sr2RuO4 as a key technology for the development of topological quantum computing. To minimize degradation, the niobium

Anomalous enhancement of upper critical field in Sr2RuO4 thin films

We report large enhancement of upper critical field Hc2 observed in superconducting Sr2RuO4 thin films. Through dimensional crossover approaching two dimensions, Hc2 except the in-plane field

Upper limit on spontaneous supercurrents in Sr 2 Ru O 4

It is widely believed that the perovskite Sr2RuO4 is an unconventional superconductor with broken time-reversal symmetry. It has been predicted that superconductors with broken time-reversal symmetry
