Authors Amend Article on Strontium Ruthenate

Because of an unfortunate miscommunication among the authors, the following corrections were not made to the published version of our article “The Intriguing Superconductivity of Strontium Ruthenate,” which appeared in the January 2001 issue of Physics Today.

In the cover caption on page 5, the alpha and beta sheets are misidentified: The alpha sheet is orange; the beta is white.

In the last sentence of the first paragraph on page 42 , the partially filled d-bands referred to parenthetically should be those of ruthenium or copper ions and not those of strontium or copper ions.

Yoshiteru Maeno’s title at Kyoto University is associate professor of physics, not professor of physics. He is also affiliated with the Japan Science and Technology Corp’s Core Research for Evolutional Science and Technology program.

On page 44 , figure 3 is based on data from S. E. Barrett, Physics Review B, volume 41, p. 6283, 1990.

In the figure in the box on page 46 , the unit on the axes is the pixel number, not the actual length (each pixel measures 7.5 mm × 7.5 mm).

On page 47 , a phrase was omitted from the last sentence of the third paragraph under “Phase-sensitive probes.” The sentence should begin: “Josephson tunneling of pairs between Sr₂RuO₄ and conventional superconductors consistent with the proposed p-wave state has been reported.”

In addition to those whose names appear in the list of acknowledgements, we would like to thank K. Ishida, M. Braden, T. Ishiguro, and Kosaku Yamada.
