Pair suppression caused by mosaic-twist defects in superconducting Sr2RuO4 thin-films prepared using pulsed laser deposition

The pairing symmetry of superconducting Sr2RuO4 is debated, and analysis is complicated by difficulties in preparing high-quality thin films. Here, thin films of Sr2RuO4 are reproducibly grown by pulsed laser deposition with a Sr3Ru2O7 single crystalline target, and the structural defect responsible...

Sumario:The pairing symmetry of superconducting Sr2RuO4 is debated, and analysis is complicated by difficulties in preparing high-quality thin films. Here, thin films of Sr2RuO4 are reproducibly grown by pulsed laser deposition with a Sr3Ru2O7 single crystalline target, and the structural defect responsible for the suppression of the superconductivity on thin films has been identified.
