Abstract

The substitutional effects to the site I of Os atom were investigated microscopically by ⁵⁵Mn zero-field NMR and NQR in β-Mn _1-xOS_x alloys. Above the Néel temperature T _N, the new set of NQR signal appears in lower frequency, suggesting the local lattice expansion around Os atom in x≤0.06. Sufficiently below T_N, NMR signal associated with the site II appears in x≥0.005. The internal field increases continuously with increasing x, which is consistent with the picture of itinerant antiferromagnet.
