High resolution neutron diffraction study to investigate quadrupolar ordering in YbRu2Ge2

DOI

Recently we have investigated magnetic and quadrupolar ordered states of YbRu2Ge2 using zero-field muon spin relaxation (µSR), neutron diffraction and inelastic neutron scattering measurements. Specific heat measurements show three successive phase transitions, with decreasing temperature from a paramagnetic to a quadrupolar state at T0 ~ 10 K, from the quadrupolar to a magnetic state at T1 ~ 6.5 K and a possible change in the magnetic ground state at T2 ~ 5.5 K. The μSR data, however, do not reveal any signature of magnetic order in the temperature range 8 - 45 K, which is further supported by neutron diffraction measurements. We therefore propose here to use high resolution neutron powder diffraction study on HRPD to investigate a small change in the crystal structure in the quadrupolar ordered state below 10K.
