AC susceptibility harmonic response in YBCO single crystals with different oxygen contents
We measured up to the seventh harmonic response of the complex ac susceptibility (χ′ n - jχ″ n ; n = 1-7) vs. temperature, in YB 2 C 3 O x single crystals with different oxygen contents (6.5 ≤ x ≤ 7). The ac field was applied in presence of an external dc field both parallel to the c-axis of the cry...
