Abstract : We present specific heat measurements of dilute AuCo and AuCoFe alloys down to 20 m °K. The hyperfine term allows to count the magnetic Co atoms which are found to be those included in groups of at least 3 Co atoms, in the AuCo alloys. On introducing Fe atoms, a large number of previously non magnetic pairs or isolated Co atoms become magnetic, due to interaction effects.
