High-pressure synthesis of quantum magnet M-YbTaO4 with a stretched diamond lattice

Nicola D. Kelly, Xuan Liang, Siân E. Dutton +2

We report bulk magnetic properties of ytterbium tantalate in its monoclinic fergusonite modification, M-YbTaO4. The spin-1/2 Yb3+ ions in this phase are arranged on a geometrically…
