A neutron diffraction study of the spin-glass-like system Y2Mo2O7 (abstract)

It has been reported recently that the crystalline, magnetically concentrated material Y2Mo2O7 displays behavior normally associated with spin-glass or cluster glass systems.1 This compound is widely reported to have the cubic pyrochlore structure, space group Fd3m, but no detailed structure determination had been reported. We have determined the crystal structure of Y2Mo2O7 from a powder profile analysis of neutron diffraction data and confirm …
