  There is intense controversy around the unconventional superconductivity in
strontium ruthenate, where the various theoretical and experimental studies
suggest diverse and mutually exclusive pairing symmetries. Currently, the
investigation is solely focused on only one material, Sr2RuO4, and the field
suffers from the lack of comparison targets. Here, employing a density
functional theory based analysis, we show that the heterostructure composed of
SrRuO3 and SrTiO3 is endowed with all the key characteristics of Sr2RuO4, and,
in principle, can host superconductivity. Furthermore, we show that competing
magnetic phases and associated frustration, naturally affecting the
superconducting state, can be tuned by epitaxial strain engineering. This
system thus offers an excellent platform for gaining more insight into
superconductivity in ruthenates.
