The equation for the relative magnetic moment μ/μsat given on p. 2, 1. 25 suffers from a typographical error. The correct equation is μ/μsat = (MCotCo − MNiFetNiFe)/(MCotCo+ MNiFetNiFe) = 0.34. There are no implications for any of the results presented, as the value given in the original article (0.34) has been calculated using the correct equation. The authors are grateful to Julia Osten for pointing out the error in the original article.
