Structure, Magnetocaloric Effect and Critical Behavior of the FeCoGdMoB Amorphous Ribbons.

The aim of the paper was to study the structure, magnetic properties and critical behavior of the FeCoGdMoB alloy. The X-ray diffractometry and the Mössbauer spectroscopy studies confirmed amorphous structure. The analysis of temperature evolution of the exponent n (ΔS = C·(B)) and the Arrott plots showed the second order phase transition in investigated material.
