Whilst the debate on the symmetry of the superconducting state in SrRuO is still ongoing, a deeper understanding of the SrRuO normal state appears crucial as this is the background in which electron pairing occurs. Here, by using low-energy muon spin spectroscopy we discover the existence of surface magnetism in SrRuO at an onset temperature higher than 50 K. Our observations set a reference for the discovery of the same magnetic phase in other materials.

Times Cited Count：9 Percentile：53.63(Physics, Multidisciplinary)In this study, we report the O 1
and Cu 2
X-ray absorption spectroscopy (XAS) and resonant X-ray emission spectroscopy (RXES) study on the A-site ordered perovskite ACuRuO (A = Na, Ca, and La). Hartree-Fock calculation and cluster model calculation were carried out to analyze O 1 and Cu 2 XAS spectra. The O 1 RXES spectra indicate that the number of O 2 holes increases in going from La to Ca to Na. In addition, the Cu 2 RXES spectra reveal that the charge-transfer energy decreases in going from La to Ca to Na.

Times Cited Count：420 Percentile：99.39(Physics, Multidisciplinary)This review presents a summary and evaluations of the superconducting properties of the layered ruthenate SrRuOas they are known in the autumn of 2011. This paper appends the main progress that has been made since the preceding review by Mackenzie and Maeno was published in 2003. Here, special focus is placed on the critical evaluation of the spin-triplet, odd-parity pairing scenario applied to SrRuO.
