Mn O 2 -modified Pb 0. 9 6 2 5 Sm 0. 0 2 5 ( Mg 1 / 3 Nb 2 / 3) 0. 7 1 Ti 0. 2 9 O 3 ceramics were prepared via a solid-state reaction approach. Results of detailed characterizations revealed that the addition of Mn O 2 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 O 2 show a high electro-strain of 0.151% at 2 kV/mm. Therefore, this study provides a new insight into the role of Mn O 2 addition in tailoring the electrical properties of the Sm-PMN-PT ceramics by acceptor doping. [ABSTRACT FROM AUTHOR]
