•Measurement of non-linear ac susceptibilities on σ-FeMo compounds.•Determination of characteristic spin-freezing and magnetic ordering temperatures.•Revealing mixed-phase ground magnetic state.•Upgrade of the magnetic phase diagram of the studied system.
Non-linear ac magnetic susceptibility terms viz. quadratic χ2 and cubic χ3 were measured versus temperature and frequency for a series of the σ-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]].
