We show that superconductivity survives up to the metamagnetic transition at $H_{\\rm m} \\approx 35$~T at low temperature. Above $H_{\\rm m}$ superconductivity is suppressed. At higher temperature superconductivity is enhanced under magnetic field leading to reentrance of superconductivity or an almost temperature independent increase of $H_{\\rm c2}$.
