The effect of the oxygenation time on the levitation force of top-seeded melt-textured YBCO domains has been investigated. The existence of an optimal annealing time, depending on the sample volume, has been brought to the fore. Longer annealings lead to a definitive deterioration of samples. A study of the levitation force versus thickness has been performed. The force has shown a monotonic dependence below a critical thickness as a function of the experimental conditions. When the sample thickness exceeds this critical value, the force has reached its maximal value and saturates.
