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 ph

Local magnetization measurements were performed by micro Hall-probe technique in the superconducting state of PrOs 4 Sb 12 , in which the time-reversal symmetry is broken. We have observed positive, i.e. ferromagnetic like, local magnetic induction just below the superconducting transition temperatu
We report NQR measurements in the filled-skutterudite compound superconductors PrðOs 1Àx Ru x Þ 4 Sb 12 ðx ¼ 0:1; 0:2Þ. Upon replacing Os with Ru, the spin-lattice relaxation rate 1=T 1 becomes proportional to temperature (T) at low temperatures far below T c , and the magnitude of ð1=T 1 TÞ lowÀT i
