Abstract:	The structure and magnetic properties of amorphous melt-spun and subsequently crystallized GdNiAl ribbons were investigated. An amorphous phase was formed after the quenching process by melt spinning with a copper wheel having a surface speed of 30 m/s. A hexagonal phase with lattice parameters a = 7.023 Å and c = 3.916 Å was formed in the GdNiAl ribbon after annealing above its crystallization temperature. Magnetic entropy change was calculated directly from isothermal magnetic measurements. The results show that both the amorphous and annealed samples have a high magnetocaloric effect, indicating that these alloys can be considered as candidates for magnetic refrigeration applications.
