Experimental Resolution

Simultaneous magnetotransport and torque magnetization measurements have been performed on superconducting (B, Ka)BiO 3 single crystals. The measurements have been carried out at very low temperatures (0.03 k < T < 2 K) and up to high magnetic fields: (30Tesla ~ Hc2(0)). The resistivity drops below the experimental resolution for a magnetic field HR(T) which is very close to the irreversibility line deduced from torque magnetometry. Close to HR(H) the resistive transition can be well by the vortex-glass scaling formalism1 suggesting that the vortex solid melts into a liquid for H > HR. Our measurements show that the irreversibility line in (K, Ba)BiO3 is closely related to this vortex glass transition line but, surprisingly, a large reversible (i.e. liquid) phase can still be observed at very low temperatures (30 m K ).
