"Co spin-echo NMR were carried out for metallic compounds Co(S,Se.-,).with pyrite structure over the entire composition range to investigate the micro-scopic magnetic properties of this system. From the results obtained, it is con-cluded that the character of Co atoms is unique in each composition with 0<,v<0.6, whereas above about x=O.S6 two kinds of Co atoms coexist, one is non-magnetic and the other is ferromagnetic with 0.85 p.. It is also shown that theeffect of electron correlations on the magnetism increases with increasing sulphurcontent. The characteristic field-induced metamagnetic transition around ,r=0.88is concluded to be due to the progressive-discontinuous transition from thenonmagnetic state to the ferromagnetic state with increasing external magneticfield. Discussions on the mechanism of the coexistence of nonmagnetic andferromagnetic Co atoms and the composition dependence of the fraction of theferromagnetic Co atoms are briefly given.
