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:Hydrogen in semiconductors and insulators plays a crucial role in their electric conductivity. Substantial experimental and theoretical efforts have been made to establish this hypothesis in the last decade, and the muon spin rotation technique has played a pioneering role. ...

摘要:Magnetic susceptibility and muon spin relaxation (µSR) measurements were performed on single-crystalline samples of SmPb3 in order to investigate magnetic properties in an antiferromagnetic state below T N ∼5 K, where a simultaneous order of dipole and ...

摘要:Magnetic susceptibility and muon spin relaxation (µSR) measurements in the intermetallic cubic compound SmIn3 with a Γ8 crystalline-electric-field ground state are reported. Anomalies corresponding to successive phase transitions were observed in the ma...

摘要:We performed muon spin relaxation measurements on randomly aligned single-crystalline samples of SmRu4P12 down to 0.02 K to investigate static and dynamical magnetic properties in low fields. The local field at the muon site develops gradually with decr...

摘要:We performed µSR measurements on a polycrystalline sample of PrPt5 from 70 K down to 50 mK in order to clarify whether PrPt5 shows bulk superconductivity or not. Unfortunately, strong local field and very low upper critical field made it difficult to ch...

摘要:A muon spin relaxation (µSR) study of the cubic Γ3 ground doublet system PrTi2Al20 is presented. The zero-field µSR rate shows no significant change while passing through the phase transition temperature T O=2.0 K, indicating that ...

摘要:We report on muon spin relaxation (µSR) studies of Sm Tr 2Al20 ( Tr : Ti, V, Cr) with a cubic Γ8 crystalline-electric-field ground state. A coherent muon spin precession was observed below the phase transition temperature in a zero applied fi...

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...

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...
