Abstract
Employing SQUID magnetometry and novel measuring and evaluation techni ques, precise information on the first penetration field can be obtain ed and used to extract H-c1. Tl- and Bi-based as well as a series of o xygen deficient Y-123 high T-c superconducting single crystals were in vestigated (H/ /c). In all cases, H-c1 is smaller than previously repo rted and can be described by BCS-theory.
