摘要：
The new method for measurements of real χ′ and imaginary χ″ parts of complex susceptibility χ=χ′+iχ″, low critical field Hc1 and critical current density jc in superconductors is proposed. The method is based on the registration of diamagnetic shielding in thin superconducting plates by a tiny Hall probe. Temperature dependences of χ′, χ″, Hc1 and jc are determined for the Bi2(Sr, Ca)3Cu2Oy single crystals. © 1990 Springer-Verlag.
