Stable elastocaloric effect in a directionally solidified Ni54Fe19Ga27 alloy under low driving stress

Applied Physics Letters
Heusler-type Ni–Fe–Ga-based alloys exhibit a large elastocaloric effect under low driving stress, yet the intrinsic brittleness of polycrystalline alloys significantly cripples their cyclic stability during mechanical cycles.
