Low-field magnetization has been investigated in powders of YBa2Cu3OT\_~ using ~amples with different maximal characteristic particle sizes dm~ of between 2.4 and 7.4 ~m. Measurements of the thermoremanent magnetization reveal the existence of a threshold field H~ corresponding to trapping of a sing
