چکیده انگلیسی
The structural, magnetic and magnetocaloric properties of HoNi2 melt-spun ribbons were investigated by X-ray diffraction, magnetization and specific heat measurements. The as-solidified ribbons samples produced are single phase with the cubic MgCu2-type crystal structure of the Laves phase (C15; space group Fd-3m), and a Curie temperature TC of 13.9â¯K. For a magnetic field change μoÎH of 5â¯T (2â¯T) applied along the ribbon length, the produced ribbon samples show a maximum magnetic entropy change ÎSMpeak of â27.2 (â16.9) J kgâ1 Kâ1, a full-width at half-maximum δTFWHM for the ÎSM(T) curve of 19 (11) K, and a refrigerant capacity, determined from the area below δTFWHM the ÎSM(T) curve, of 388 (145) Jkgâ1; the adiabatic temperature change ÎTad at 2â¯T is 6.7â¯K. Whereas crystal structure and intrinsic magnetic properties are in good agreement with the experimental data previously reported in literature for bulk polycrystalline alloys, the magnetocaloric parameters at 2â¯T are markedly superior owing to the favorable combination of partial texture with the anisotropic behavior of magnetization.
