Erratum to “Magnetic resonance investigations on NaFe4Sb12” [Journal of Magnetism and Magnetic Materials 272–276 (2004) 830–832]

Abstract The hyperfine coupling constants A α on p. 831 of NaFe 4 Sb 12 (Fig. 1) are too large by a factor of 10. This error comes from conversion of kOe and T. The correct hyperfine coupling constants are determined to be A α 1 =−1.449 kOe/ μ B above T C and A α 2 =−1.155 kOe/ μ B below T C . We apologize for this error and any confusion that they may have caused. The results and conclusions of our paper remain unaffected.
