Abstract:
We measured the first and third harmonics of the complex ac susceptibility in YBCO single crystals with different oxygen contents (6.5 ≤ × ≤ 7). The amplitude of the ac field was varied in presence of an external dc field both applied parallel to the c-axis of the crystals. We give evidence that deoxygenation leads to a reduction of the bulk pinning strength and consequently to a stronger contribution of geometrical barriers. These results support the recently reported investigations showing that deoxygenation makes the YBCO crystals more anisotropic reducing the effective bulk pinning for quasi-two-dimensional vortices. We also show measurements for the same crystals with the ac field applied perpendicular to the c-axis.
