Poling and structuring of ferroelectric domains form the basis for developing prospective applications using materials from the lithium-niobate (LN) family. Applications range from second harmonic generation to electro-optic modulators or surface acoustic wave devices. In the work presented here, hysteresis measurements are used as a standard method to quantitatively determine the poling properties of these ferroelectrics, including their spontaneous polarization Ps as well as their forward and reverse coercive fields Ec,+ and Ec,?. Systematic measurements that depend on parameters such as the ramp rate R of the applied poling voltage and the waiting time twait between domain inversions are investigated and compared between the congruent variants of LN, lithium tantalate (LT), their magnesium-doped analogues, and stoichiometric LN. For bulk magnesium-doped LN, for example, it is found that the resulting coercive field strongly depends on the speed of the voltage ramp, with Ec$E_c$ values ranging from 11 to 21?kV?mm?1. These investigations are used as fundamental input for poling ferroelectric lithium niobate-tantalate solids (LNT), a system that offers a high potential for tuning the material parameters beyond what is possible for LN or LT.
