Mn-modified ceramics were prepared via a solid-state reaction approach. Results of detailed characterizations revealed that the addition of Mn has influence on the grain size, and all samples exhibit a pure perovskite structure. As the content of manganese increases, the volume of tetragonal phase increases. The ceramics with 1.5 mol.% Mn show a high electro-strain of 0.151% at 2 kV/mm. Therefore, this study provides a new insight into the role of Mn addition in tailoring the electrical properties of the Sm-PMN-PT ceramics by acceptor doping.
