Dielectric signatures of crystal-field and low-temperature correlated dynamics in NdMgAl11O19

Sonu Kumar, Gaël Bastien, GaÃ«l Bastien +5

We report dielectric spectroscopy of single-crystalline \ce{NdMgAl11O19}, a magnetoplumbite hexaaluminate in which localized \ce{Nd^{3+}} moments coexist with a polarizable \ce{AlO…

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…

Quantum disordered ground state and relative proximity to an exactly solvable model in the frustrated magnet CeMgAl $_{11}$ O $_{19}$

G. Bastien, A. EliÃ¡Å¡, A. Eliáš +19

The magnetic properties of the triangular magnet CeMgAl $_{11}$ O $_{19}$ were investigated by magnetization and specific heat measurements down to $T = 0.03$ K on single crystals grow…
