Neutron diffraction and susceptibility measurements have been performed to investigate the anomalous transition from antiferro- to ferromagnetic order which takes place in the ternary intermetallic compound TbNiAl when Ni is substituted for Cu within

Production of amorphous alloys by solid state reactions (SSR) has attracted much interest during the last few years. One of the methods to induce such a reaction is the irradiation of suitable crystalline alloys by fast particles. Examination of this

The direction dependence of the diffusion coefficient of 113 Sn has been measured in single crystals of Ni 61 Sn 39 by the layer grinding technique. The activation energies for diffusion parallel and perpendicular to the hexagonal c-axis are 2.93 and

The temperature dependence of the lattice parameters in the beta -phase (BCC structure) of pure Zr and Zr-2 at.%Co was determined between 900 and 1550 degrees C by neutron diffraction. All diffraction patterns show a high diffuse background, which is

In TbNiAl, which adopts the hexagonal ZrNiAl-structure, the Tb-site forms a triangular lattice in the a - b plane. The coupling between nearest neighbours was shown to be antiferromagnetic, giving rise to the formation of frustrated moments of Tb. Tb

The phonon dispersion of the high-temperature bcc phase of Hf has been measured. The dispersion resembles very much those of the other group-IV metals: bcc Ti and bcc Zr. It is dominated by the low-energy L 2/3(1,1,1) mode and by the low-energy T{sub

The diffusion of Ni-63 and Sb-124 is measured on single crystals of Ni53Sb47 by the sectioning technique. Diffusion coefficients for transport parallel and perpendicular to the crystallographic c-axis (D‖ and D⟂) and activation energies are repor

The energy dependence of stopping powers for 1–2 MeV α particles and 1–2.7 MeV tritons was determined by using the 6 Li( n , α) T reaction in LiF and several Li alloys. The results are analysed to obtain both absolute stopping powers and the ef
