Paper Abstract

The magnetic properties of thick film of Ba1-xKxBiOy with x equals 0.36, Tc equals 30 K and thickness of 18 micrometers were investigated using SQUID-magnetometer at external fields up to 5 T. It is shown that field dependencies of the critical current Jc(B) in the range of temperature 5 - 20 K and fields above the peak-effect field Hp are well described in terms of the model of small bundle collective pinning regime.
