Abstract
Magnetization measurements have been performed on the cubic (K, Ba)BiO3 sup erconductor (T-c similar to 30K). The reversible part of the magnetization varies linearly with lnH in both liquid and solid phases. The M-rev curves never cross each other but partial derivativeM/partial derivative ln H stro ngly deviates from the standard London model at high temperature. Keywords : Reversible Magnetization, Cubic Bismuthates.
