Metamagnetic transitions and magnetocaloric effect in epitaxial Ni?Co?Mn?In films
Result description
Due to their large strains and multifunctionality, magnetic shape memory alloys are of particular interest for microsystems. Here epitaxially grown metamagnetic Ni?Co?Mn?In films on MgO (001) are analyzed which exhibit a magnetically induced austenite transition. This opens the way to use Ni?Co?Mn?In films in microactuators combining high stroke with high forces. Additionally these films exhibit an inverse magnetocaloric effect with an entropy change of 8.8 J kg1 K1 in 9 T at 353 K. The high surface-to-volume fraction of films promises a fast heat exchange, which is beneficial for efficient magnetic cooling.
