文摘

The working temperature range is expanded by substituting Ho with Gd atoms. GdxHo3−xAl2 (x = 1.0–2.5) exhibit nearly constant ΔSM in 100–250 K. A gaint RC is obtained in GdHo2Al2 due to partial overlap of successive ΔSM peaks. GdHo2Al2 is good candidate for magnetic refrigeration of natural gas liquefaction.
