Abstract
The single-crystal susceptibility and magnetization hysteresis of YBa2Cu3O7 and YBaCu3O6.6 with Tc’s of 90K and 58K, respectively, were measured on the twin-free samples. The detwnning and retwinning processes are described for overdoped and underdoped regimes. The critical current in the untwinned overdoped YBa2Cu3O7 is dramatically lowered relative to both oxygen-deficient and twinned crystals.
