PHYSICS Correction for “Magnetic stripes and skyrmions with helicity reversals,” by Xiuzhen Yu, Maxim Mostovoy, Yusuke Tokunaga, Weizhu Zhang, Koji Kimoto, Yoshio Matsui, Yoshio Kaneko, Naoto Nagaosa, and Yoshinori Tokura, which appeared in issue 23, June 5, 2012, of Proc Natl Acad Sci USA (109:8856–8860; first published May 21, 2012; 10.1073/pnas.1118496109).
The authors note that on page 8856, right column, first full paragraph, line 23, “x = 0.16” should instead appear as “x = 1.6.” The same error appears on page 8860, in the Methods section, line 1, where “x = 0.16” should also appear as “x = 1.6.”
