Abstract

Double superconducting transition in PrOs4Sb12 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 Tc are stabilized in the crystal. The characteristics of superconducting double transition in PrOs4Sb12 are discussed based on the local magnetization measurements at multi-points.
