Abstract

The investigation of ⁸⁹Y nuclear magnetic resonance (NMR) spectrum and spin lattice relaxation was presented in the magnetically frustrated pyrochlore Y₂Mo₂O₇. A nonrandom distortion of the Mo sublattice starting at temperature as high as 200 K was observed. The low temperature spectrum was revealed to be constructed from multiple peaks and each peak was shifted by a different amount. The discrete lattice distortions which relieved the frustation and reduced the system's energy were found to be responsible for the existence of the spectrum.
