Abstract

We performed local magnetization measurements using micro-Hall probe in filled skutterudite PrOs4Sb12, which shows a superconducting state with broken time-reversal symmetry. It turns out that there appears a remarkable dip in the local magnetization hysteresis near zero field, which is characteristic of chiral superconductors, while temperature dependence of local magnetization shows no distinctive anomaly related to the spontaneous field. Possible situations of the spontaneous field is discussed from the results of local magnetization.
