"Irreversibility line and anisotropy of SmBa2Cu3O7-δ with varying oxygen content";
Physica C: Superconductivity and its Applications,
We report on magnetization and torque measurements of SmBa2Cu3O7-δ (Sm123) single crystals with an
oxygen content 7-δ = 6.60, 6.70 and 6.78. The anisotropy increases from 40.1 ± 0.4 to 56.4 ± 0.7 with
decreasing oxygen content from 6.78 to 6.70. The crossover field, Hcr, where the irreversibility line
changes slope, is lowered for crystal with a lower oxygen content. The Hcr values are higher for Sm123
than for YBa2Cu3O7-δ (Y123) single crystals. The anisotropy dependence on the oxygen content is compared
to that of Y123.
