The oxygen isotope effect of the ferromagnetic transition in itinerant ferromagnet strontium ruthenate SrRuO3 with a Curie temperature Tc of 160 K is studied. We observed for the first time a shift of ∆Tc ~ 1 K by oxygen isotope substitution of (16)O → (18)O in SrRuO3 by precise measurements of DC and AC magnetizations. The results surprisingly lead to the(More)
