Sr0.61Ba0.39Nb2O6 crystals grown by a modified double-crucible Stepanov technique have coercive fields independent of thickness. The coercive field is about 250 V/mm as measured from the ferroelectric hysteresis loop. However, the coercive field is found to depend strongly on the ramp rate. Dielectric measurements revealed a diffused phase transition at about 352 K and a Curie constant of about $4.5 \times 10^{5}$ K.
