Giant elastocaloric effect in directionally solidified Ni-Mn-In magnetic shape memory alloy Academic Article uri icon

The textured microstructure significantly enhances the ductility of Ni-Mn-based MSMAs, which allows obtaining the martensitic transition characteristics of polycrystalline samples in a uniaxial stress field. A significant cooling level of about 4 K is measured when the stress is released. The experimentally measured temperature changes are found to be in good agreement with the theoretically calculated values.
