In order to use the magnetic shape memory alloy Ni-Mn-Ga with its high achievable strain of up to 10% for microactuators, freestanding epitaxial films are required. Here we show that these conditions can be fulfilled when using chromium as a sacrificial layer. The low misfit towards Ni-Mn-Ga enables
