Isotope effect in superconducting n-doped SrTiO(3)

We report the influence on the superconducting critical temperature T(c) in doped SrTiO(3) of the substitution of the natural (16)O atoms by the heavier isotope (18)O. We observe that for a wide range of doping this substitution causes a strong (~50%) enhancement of T(c). Also the magnetic critical...
