Texture Investigations at Low Temperatures by Neutron Diffraction Shown on the Example of TbAg

Abstract

The first low temperature texture investigation by neutron diffraction is presented. Pole figures are collected on a special full circle Eulerian cradle mounted completely inside a helium cryostat. Nuclear and magnetic pole figures of antiferromagnetic TbAg are measured at 300 and at 77 K respectively. The bulk specimen revealed only a weak texture. Magnetic satellite reflections presumed for special sample orientations were not observed.
