Abstract
We present magnetoresistance measurements up to 20 T performed on superconducting (K, Ba)Bi(Formula presented) single crystals ((Formula presented) K). The foot of the transition curves can be fitted to (Formula presented) and the (Formula presented) curves exhibit a power law behavior at the melting temperature ((Formula presented)). This shows that a vortex glass transition exists in this three-dimensional superconductor. The fluctuations of the conductivity in the vicinity of the mean field transition are discussed through the scaling procedure developed by Ullah and Dorsey. An (Formula presented) phase diagram has been deduced from the data.
