      abstract     = {Epitaxial a-axis oriented NaNbO3 films are grown on (110)
                      oriented NdGaO3 substrates. The lattice mismatch between
                      substrate and film leads to compressive strain of $0.7\%$
                      in the a-c plane. As a consequence the in-plane permittivity
                      and tunability are strongly enhanced compared to bulk NaNbO3
                      and a pronounced maximum in the temperature dependence of
                      the permittivity occurs. Below the maximum at Tmax250K
                      ferroelectric behavior is observed that seems to vanish
                      above Tmax. The pristine phase of the film at T<Tmax is
                      antiferroelectric and is easily suppressed by small applied
                      electric fields. The ferroelectric phase shows a relaxor
                      type behavior.},
