The pyrochlore, Ho2Ge2O7, 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 wtih reverse Monte Carlo (RMC) refinements, give unique information about the spin ice state in Ho2Ge2O7, demonstrating consistency with spin ice behavior.
