Spin-orbit-entangled $J_{eff} = \frac{1}{2}$ magnetism and unconventional spin freezing in the bond-disordered pyrochlore antiferromagnet NaCdCo $_{2}$ F $_{7}$

Andrej Kancko, Hironori Sakai, Javier Herrero-Martín +6

Bond disorder in frustrated pyrochlore antiferromagnets can give rise to fundamentally different quantum ground states depending on the nature of the local magnetic moments. Here,…

Structural and spin-glass properties of single crystal $J_{e f f}$ = 1/2 pyrochlore antiferromagnet NaCdCo $_{2}$ F $_{7}$ : correlating $T_{f}$ with magnetic-bond-disorder

Andrej Kancko, Gerald Giester, Ross H. Colman

Weak bond disorder disrupts the expected spin-liquid ground-state of the ideal $S$ = 1/2 Heisenberg pyrochlore antiferromagnet. Here we introduce a single crystal study of the stru…
