【 摘 要 】

Non-linear ac magnetic susceptibility terms viz. quadratic chi(2) and cubic chi(3) were measured versus temperature and frequency for a series of the sigma-phase Fe100-xMox (47 <= x <= 53) compounds. Clear evidence was found that the ground magnetic state of the samples is mixed i.e. constituted by a mixture of two phases: a spin glass (SG) and ferromagnetic (FM) clusters, hence the magnetism of the investigated samples can be regarded as re-entrant. Based on the present data, previously reported magnetic phase diagram has been upgraded [Przewoznik and Dubiel (2015) [12]]. (C) 2016 Elsevier B.V. All rights reserved.
