摘要：

The London penetration depth lambda(T) of Ba0.625K0.375BiO3 was determined for the first time from the spin-rotation-relaxation of muons implanted into a high purity polycrystalline sample, field-cooled in 0.1 and 0.3T external fields. The data showed that over 90% of the sample was superconductive. The temperature dependence of lambda indicated weak-coupling BCS behaviour, with T(c) = 26K and lambda(0) = 340nm.
