Query: 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 direction is dramatically
enhanced compared to bulks, following a definite relation distinct from bulk
one between Hc2 and the transition temperature. The anomalous enhancement of
Hc2 is highly suggestive of important changes of the superconducting
properties, possibly accompanied with rotation of the triplet d-vector. Our
findings will become a crucial step to further explore exotic properties by
employing Sr2RuO4 thin films.
