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-MartÃn +5

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,…

Absence of Long-Range Order and Magnetic Anisotropy in the Triangular Magnet NdMgAl $_{11}$ O $_{19}$

Sonu Kumar, GaÃ«l Bastien, Jan ProkleÅ¡ka +9

We investigated the rare-earth triangular-lattice antiferromagnet NdMgAl $_{11}$ O $_{19}$ using single-crystal magnetization (1.8~K $\leq T \leq$ 300~K, $I^¼_{0} H \leq 7$ ~T) and specif…
