Abstract:

In the present work we have measured the magnetization relaxation at T = 4-2 K in two substantially different superconductors: BaPbo.~sBio.250 3 (BPB, T~ 10K, Hcx ~ 12 Oe) and YBa2Cu307_ x (YBCO, T~ ~ 92 K). The SQUID magnetometer with active and passive electromagnetic field shielding guaranteed measurements for H up to 900 Oe. The polycrystalline specimens were prepared by the solid-state synthesis method.
