Magnetic ordering in rare earth metal dysprosium revealed by neutron diffraction studies in a large-volume diamond anvil cell
Abstract
A high-pressure low-temperature neutron diffraction study has been carried out on rare earth metal Dysprosium (Dy) to 10.8 GPa and 8 K in a large-volume diamond anvil cell using a spallation neutron source. Dy crystallizes in an ambient pressure hexagonal close packed phase and forms an incommensurate helical antiferromagnetic phase, marked by the appearance of superlattice magnetic peaks below 176 K with a turn-angle between the hexagonal layers that increases both with increasing temperature and pressure. The ferromagnetic transition below 87 K is marked by an increase in intensity of nuclear peaks with disappearance of magnetic superlattice reflections. Dy transforms to an alpha-Samarium (α-Sm) phase at 7 GPa and only ferromagnetic ordering is observed for this high pressure phase. Here, the ferromagnetic transition is observed at 59 K in the α-Sm phase at 10.8 GPa in close agreement with the magnetic ordering temperature obtained from electrical transport measurements. In the entire pressure-temperature range of this study, Dy shows a negative thermal expansion coefficient of as much as -2.5 % in the magnetically ordered phases between 200 K and 8 K.
