The Cu-NMR spectrum below T MI is broadened and split into four Cu signals with sizable electric quadrupole interactions. The NMR results are consistent with the charge ordering of Ir^3+ and Ir^4+ and the spin dimerization of Ir^4+ spins, as revealed by a recent X-ray study.SpringerJournal Articleapplication/pdfhttp://hdl.handle.net/2115/8373https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/8373/1/NQI2004spinelmuscriptprer.pdf0304-38431572-9540Hyperfine Interactions1591-41811852005-12enginfo:doi/10.1007/s10751-005-9094-3The original publication is available at www.springerlink.comauthor
