    We show that tetragonal single-domain states of Mn-doped NBT-6 %BT single crystals can be stabilized by poling along a [001] direction. For carefully prepared crystals, the piezoelectric coefficient d33 can reach 570 pC/N. When poled along non-polar directions, the crystals exhibit ferroelectric domain structures consistent with tetragonal micron-sized domains, as revealed by optical observation and Raman spectroscopy. The multidomain crystals have lower d33 values, 225 and 130 pC/N for [011] and [111]-oriented crystals, respectively.
