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... -
Diamagnetic doping in the 3D spin liquid PbCuTe2O6 compound
PbCuTe2O6 offers the first opportunity to study a 3D quantum spin liquid well modeled by the simple Heisenberg Hamiltonian on a highly frustrated lattice coined... -
Spin dynamics in the S=1/2 zigzag spin chain magnets K2CuCl2SO4 and Na2CuCl2SO4
We have recently succeeded to synthesize pure-phase of K2CuCl2SO4 and Na2CuCl2SO4. In addition, we succeeded to grow the large single crystals (~ 10×10×10 mm3). K2CuCl2SO4 is a... -
Investigating the superconducting pairing symmetry of heavy fermion supercond...
The first discovered heavy fermion superconductor CeCu2Si2 had been believed to have d-wave pairing symmetry for many years. However, recent experiments on CeCu2Si2 discovered...
