Abstract:

The crystal structure, martensitic transformation and magnetocaloric effect have been studied in all-d-metal Ni35Co15Mn33Fe2Ti15 alloy ribbons with different wheel speeds (15 m/s (S15), 30 m/s (S30), and 45 m/s (S45)). All three ribbons crystalize in B2-ordered structure at room temperature with crystal constants of 5.893(2) angstrom, 5.898(4) angstrom, and 5.898(6) angstrom, respectively. With the increase of wheel speed, the martensitic transformation temperature decreases from 230 K to 210 K, the Curie temperature increases slightly from 371 K to 378 K. At the same time, magnetic entropy change (Delta S-m) is also enhanced, as well as refrigeration capacity (RC). The maximum Delta S-m of 15.6(39.7) J/kg center dot K and RC of 85.5 (212.7) J/kg under Delta H = 20 (50) kOe (1 Oe = 79.5775 A center dot m(-1)) appear in S45. The results indicate that the ribbons could be the candidate for solid-state magnetic refrigeration materials.
