摘要:Muonium (Mu) centers formed upon implantation of μ + in a solid have long been investigated as an experimentally accessible model of isolated hydrogen impurities. Recent discoveries of hydridic centers formed at oxygen vacancies have stimulated a renewed interest ...

摘要:Unconventional superconductivity based on the strong correlation of electrons is one of the central issues of solid-state physics. Although many experimental techniques are appropriate for investigating unconventional superconductivity, a complete perspective has not been establi...

摘要:Superconducting and magnetic properties of the heavy fermion superconductor CePt3Si were studied in a polycrystalline sample by means of the muon spin rotation and relaxation method. The muon Knight shift is invariant on passing the temperature through T c d...

摘要:We report that the muon spin relaxation rate under zero-external field in the heavy-fermion compound Ce Tr In5 ( Tr =Ir, Co) is independent of temperature down to 20 mK, demonstrating the absence of magnetism due to long-range magnetic order and/or to the breakdow...

摘要:Magnetic and superconducting properties were studied in a polycrystalline sample of the heavy fermion superconductor CePt3Si by means of the muon spin rotation and relaxation method. The lower limit of the penetration depth was obtained to be ∼1000 nm. An appearan...

摘要:The magnetic properties of Ce0.8Nd0.2B6 single crystals have been studied by muon spin relaxation (µSR). The lack of a clear muon spin precession in phase IV indicates that no commensurate long-range magnetic order is present in this phase. M...

摘要:We report on the magnetic phase diagram of a hole-doped cuprate Ca2- x Na x CuO2Cl2, which is free from buckling of CuO2 planes, determined by muon spin rotation and relaxation. It is characterized by a quasi-static spin...

摘要:A strong correlation between field-induced antiferromagnetic (AF) order and superconductivity is demonstrated for an electron-doped cuprate superconductor, Pr1- x LaCe x CuO4-δ (PLCCO). In addition to the specimen with x =0.11 (which is close...

摘要:We report zero-field µ+SR measurements made at J-PARC on CeRu2Al10. Below the phase transition temperature T 0∼27 K, a clear modulation of µ+ polarization due to an internal field is observed, indicating that magnetic or...
