Abstract
A sigma-phase Fe65.9V34.1 alloy was investigated with the AC magnetic susceptibility as a function of temperature, frequency and external magnetic field. Evidence was found that its magnetism shows features characteristic of a reentrant behavior viz. two transitions: first at TC ∼312 K from the paramagnetic state into a collinear ferromagnetic one, and second at Tf ∼302 K to a mixed state (sometimes referred to as a ferromagnetic or re-entrant spin glass) which, finally, at a lower temperature (TRSG ∼60 K) transforms to a state where replica symmetry is broken. The frequency dependence of Tf is lower than that of canonical spin glasses, a feature that in the light of a high concentration of magnetic carriers can be understood in terms of a weak coupling between magnetic clusters.
