Negative thermal expansion in the plateau state of a magnetically-frustrated spinel [PDF]

, 2019
We report on negative thermal expansion (NTE) in the high-field, half-magnetization plateau phase of the frustrated magnetic insulator CdCr2O4. Using dilatometry, we precisely map the phase diagram at fields of up to 30T, and identify a strong NTE ...
