We have found that in pure Sr2RuO4 uniaxial pressure along the c axis enhances the onset temperature of the superconducting transition up to 3.2 K from 1.5 K [1]. This result is surprising because it is known that Tc is suppressed under hydrostatic pressure [2]. In this presentation, I will discuss a possible mechanism of the enhancement of Tc.
