## Description

- description: "We report bulk magnetic properties of ytterbium tantalate in its monoclinic
    fergusonite modification, M-YbTaO4 . The spin- 12 Yb3+ ions in this phase are arranged
    on a geometrically frustrated “stretched diamond” lattice. M-YbTaO4 cannot be
    prepared at ambient pressure and was instead prepared in a belt-type apparatus
    at 6 GPa and 1800 ◦C. Susceptibility and specific heat data show no long-range
    ordering down to 1.8 K and are consistent with a Jeff = 12 Kramers doublet which
    splits in an applied field. Furthermore, under high-pressure synthesis the entire
    solid solution YbNbx Ta 1−x O4 (0 . x . 1) can be stabilized in the M phase, in
    contrast to ambient-pressure synthesis which favors the competing M. phase for
    Ta-rich compositions. Subsequent\r\nannealing of the Nb-Ta mixed samples resulted
    in color changes, suggesting oxygen deficiency in some of the as-prepared high
    pressure samples. There was little variation in the bulk magnetic properties upon
    varying either the Nb/Ta ratio or the annealing conditions."
