Evolution of the long-range ferromagnetic order at a transition from a ferromagnet to a spin glass

An anomalous feature has been observed in the nonlinear magnetic susceptibility of a disordered FeNiCr alloy below the Curie point. This feature is linked with a disruption of the long-range ferromagnetic order and the appearance of a spin-glass state.
