QUANTUM DIFFUSION AND LOCALIZATION OF POSITIVE MUONS IN SUPERCONDUCTING ALUMINUM
- 1995

Ingår i: PHYSICAL REVIEW B-CONDENSED MATTER. - : AMER INST PHYSICS. - 0163-1829. ; 52:9, s. 6417-6423
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Large differences were observed, indicating that the diffusion mechanism depends sensitively on the interaction between the muon and the conduction electrons. The samples were high-purity aluminum doped with controlled amounts of lithium. The lithium impu

-
Tidskriftsartikel (refereegranskat)abstract
- Positive muons implanted in proton-conducting oxides can be used to gain insight into the diffusion and trapping behaviour of light particles in these materials which are used as solid oxide electrolytes in high-temperature fuel cells. We have studied bot

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Trapping as a main feature of proton diffusion in proton conducting oxides was investigated by means of muon spin relaxation measurements, with the positive muon as tracer. In Sc-doped SrZrO3, a system with representative physicochemical properties and fa

Tidskriftsartikel (refereegranskat)abstract
- After a short introduction to mu SR with respect to the study of magnetic properties, followed by a brief outline of the principle of the high pressure-low temperature mu SR spectrometer installed at the Paul Scherrer Institute, we discuss some measuremen

mu SR studies of magnetic correlations in Pt and Cu doped CeNiSn
- 1997

Ingår i: PHYSICA B. - : ELSEVIER SCIENCE BV. - 0921-4526. ; 230, s. 655-657
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The development of magnetic correlations at low temperatures was studied by muon spin relaxation (mu SR) and specific heat measurements in CePtxNi1-xSn (x = 0.12, 0.2) and CeCuxNi1-xSn (x = 0.05, 0.1, 0.2). Doping with Pt up to 20% increases the magnetic

Tidskriftsartikel (refereegranskat)abstract
- The Mn ions occupy three different sites (8i, 8j, 8f) in equal population in YMn12, which has the tetragonal ThMn12 structure with space group I4/mmm. They possess a different magnetic moment at the 8f site (0. 14 mu(B)) compared to the 8i and 8j sites (0

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The temperature dependence of the muon spin relaxation rate lambda was measured in two samples of CeNiSn with markedly different impurity content and in the quasi-ternary compounds CePtxNi1-xSn (x = 0.12, 0.2) and CeCuxNi1-xSn (x = 0.05, 0.1, 0.2) in orde

Magnetic properties of GdMn2 from mu SR

Ingår i: PHYSICA B. - : ELSEVIER SCIENCE BV. - 0921-4526. ; 289, s. 265-268
-
Tidskriftsartikel (refereegranskat)abstract
- GdMn2 has a Neel transition around 100 K and a second magnetic transition near 40 K, which is considered a Curie point. The mu SR data show that both the Gd and the Mn sublattice order at T-N, in contrast to a published model. Using the signal from muons
