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 (övrigt vetenskapligt/konstnärligt)abstract
- Muon spin rotation (mu SR) data on a single crystalline sample of Dy have been obtained as function of temperature and applied hydrostatic pressure. The discontinuity observed in our new data at the phase transition at 85 K strongly suggests that the muon

Ferromagnetic erbium studied by mu SR

Ingår i: HYPERFINE INTERACTIONS. - : BALTZER SCI PUBL BV. - 0304-3843. ; 104:1-4, s. 293-299
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The ferromagnetic cone phase of erbium has been studied with mu SR. Two precessing muon signals were observed with nearly equal intensities at T approximate to 15 K. At lower temperatures, one of the signals is gradually reduced and disappeared below 5 K.

mu SR investigations of gadolinium in the paramagnetic regime near the ferromagnetic transition

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We report on the measurements of the muon relaxation rate in gadolinium (Gd) in the critical regime down to T - T-C = 0.1 K. The results are compared to the predictions of mode-coupling calculations for a uniaxial and dipolar ferromagnet. One observes tha

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
