Abstract
The shape memory characteristics of Ni45Mn36.5Co5In13.5 single crystals, which exhibit magnetic field-induced phase transformation (FIPT), were investigated under compression along the [1 0 0] orientation. The effects of temperature and bias stress on the pseudoelastic response and the shape memory effect were explored. The crystals demonstrated large stress and temperature hysteresis with a fully reversible transformation strain of 5.4%, the ramifications of which on the field requirement for FIPT are discussed.
