We have observed the de Haas-van Alphen (dHvA) oscillation of Sr 2 RuO 4 , the layered perovskite superconductor not based on copper. The Fermi surface was confirmed to be a corrugated cylinder. This characteristic feature of the Fermi surface brings about a large angular dependence of the dHvA amplitude, which is explained by the spin-splitting zero in the dHvA oscillation and the Yamaji effect.
