Direct magnetocaloric measurements of Fe-B-Cr-X (X = La, Ce) amorphous ribbons. Journal of Applied Physics, 110, 023907-1-023907-4.0021-8979 (impreso)http://hdl.handle.net/11441/67228A procedure has been developed to directly measure the adiabatic temperature change of amorphous melt-spun Fe-based ribbons displaying attractive room temperature magnetocaloric properties. Polycrystalline Gd ribbons are used as a reference material to compensate for the contribution of the sample holder to the experimental values. Fe78B12Cr8Ce 2 and Fe75B12Cr8Ce5 melt-spun ribbons exhibited a peak adiabatic temperature change (ΔT adpk) ∼ 58% larger than Co82.9Si 5.9Fe4.5Cr4B2.7 amorphous ribbons. The ΔTadpk in Fe78B12Cr 8Ce2, Fe75B12Cr8Ce 5, and Fe79B12Cr8La1 ribbons displayed ∼ 18-33% enhanced ΔTadpk compared to a GdAl2 alloy.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1063/1.3613666
