✦ Synopsis

Double superconducting transition in PrOs 4 Sb 12 has been studied carefully by local magnetization measurements using Hall probe array. Local magnetization curves for each element of the Hall probe reveal that there exists a significant difference in the transition temperature at each point; two phases which give different T c are stabilized in the crystal. The characteristics of superconducting double transition in PrOs 4 Sb 12 are discussed based on the local magnetization measurements at multi-points.

We performed local magnetization measurements in the superconducting state of PrOs 4 Sb 12 using micro-Hall probe. For a magnetic field applied along one of the principal axes, a remarkable dip structure in the magnetization hysteresis loop was observed close to zero local magnetic induction. The an
