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