Abstract: Solid phase stability and magneto-caloric effect of a ternary Gd50Co48Fe2 amorphous as-spun ribbons was studied in this work. The magnetization curve was measured at temperature range from 200 to 360 K. Subsequently the isothermal magnetization curves were measured as well at temperatures ranging from 200 to 350 K and at magnetic field between 1 to 5 T, using SQUID. Based on these experimental data, the magnetic entropy changes were determined. Thermal stability and phase composition of amorphous alloy was experimentally confirmed by difference scanning calorimetry and synchrotron X-ray diffraction. At elevated temperatures two crystallization events were observed. It has been found that the investigated alloy is a prospective aspirant for magnetic cooling devices.
