superlattice

The putative chiral spin-triplet superconductivity in ruthenate is under intense controversy, where the various theoretical and experimental studies discuss the diverse alternative pairing symmetries. Currently, the investigation is solely focused on only one material, Sr₂RuO₄, and the field suffers from the lack of comparison target. Here, employing density functional theory-based analysis, we show that the heterostructure composed of SrRuO₃ and SrTiO₃ is inherent with all the key characteristics of Sr₂RuO₄, and eventually can host superconductivity. Furthermore, we show that the competing magnetic phases and associated frustration entangled with the superconducting state can be tuned by epitaxial strain engineering. This system offers an excellent platform for the study of
superconductivity of the ruthenate system.
