Abstract

The pyrochlore Ho ₂Ge ₂O ₇ is a new highly correlated spin ice material. Physical property measurements, including x-ray diffraction, dc susceptibility, and ac susceptibility, confirm that it shares the distinctive characteristics of other known spin ices. Polarized neutron scattering measurements on a powder sample, combined with reverse Monte Carlo (RMC) refinements, give unique information about the spin ice state in Ho ₂Ge ₂O ₇. RMC refinements are used to fit the powder magnetic diffuse scattering and predict the single-crystal magnetic scattering of Ho ₂Ge ₂O ₇, demonstrating consistency with spin ice behavior.
