Time reversal symmetry breaking in superconducting PrOs4Sb12 and its alloys
In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in... -
Broken Time Reversal Symmetry in Superconducting (Pr, Ce)Pt4Ge12 alloys
The unconventional filled skutterudite superconductor, PrPt4Ge12(Tc ~ 7.9 K), was recently discovered, for which zero field muon spin relaxation (ZF-MuSR) experiments reveal... -
Penetration depth in isovalent Ru substitution Ba(Fe$_{1-x}$Ru$_x$)$_2$As$_2$
The investigation of the recently discovered high-Tc superconductors based on iron pnictides, has attracted great attention. Much effort has been devoted to determining the...
