Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We have studied the magnetic spinel (Zn)[Fe-2]O-4 (T-N approximate to 10.5 K) and the non-magnetic spinels (Zn)[Al-2]O-4, (Zn)[Ga-2]O-4, (Zn)[ZnTi]O-4 and (Zn)[ZnSn]O-4, both with surface and decay channel muons. In (Zn)[Fe-2]O-4 the relaxation rate incre

Tidskriftsartikel (refereegranskat)abstract
- mu SR studies in zero, longitudinal and transverse fields were carried out in the temperature range between 2 and 150 K on a polycrystalline powder sample. The data confirm the presence of two magnetic states, but each contains differently correlated spin

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

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

SPIN FREEZING IN THE KONDO METAL CEPTSN

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Muon spin rotation/relaxation (mu SR) data for the antiferromagnetic Kondo metal CePtSn are presented, especially for the region around its magnetic transition. We find above 8.8 K spectra typical for a paramagnet with fast spin fluctuations and below 7.5

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

-
Tidskriftsartikel (refereegranskat)abstract
- Magnetic order (including spin freezing) is absent down to similar to 15 mK in CeNiSn due to the dominance of coherent spin fluctuations caused by the Kondo interaction. Partial replacement of Ni by Cu or Pt induces a highly disordered magnetic state. The

-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Recent results of thermodynamic and transport measurements on CeNiSn at low temperatures show a strong dependence on sample purity. A lower impurity content leads to a more metallic behavior of CeNiSn. We present muon spin relaxation (mu SR) spectra at T

Magnetic properties of GdMn2 from mu SR

-
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
