Dielectric signatures of crystal-field and low-temperature correlated dynamics in NdMgAl11O19
Sonu Kumar, Gaël Bastien, Gaël 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 NdMgAlO
Sonu Kumar, Gaël Bastien, Jan Prokleška +9
We investigated the rare-earth triangular-lattice antiferromagnet NdMgAlO using single-crystal magnetization (1.8~K 300~K, ~T) and specif…
Crystal-Field--Driven Magnetoelectricity in the Triangular Quantum Magnet CeMgAlO
Sonu Kumar, Gaël Bastien, Gaël Bastien +10
We report dielectric and magnetoelectric studies of single-crystalline \ce{CeMgAl11O19}, a Kramers triangular magnet embedded in a polarizable hexaaluminate lattice. In zero magnet…
Induced quantum magnetism on a triangular lattice of non-Kramers ions in PrMgAl11O19
S. Kumar, M. Klicpera, A. Eliáš +9
We report the magnetic properties of the quantum triangular lattice antiferromagnet (TLAF) PrMgAl11O19 through magnetization and specific heat measurements. Strong magnetic anisotr…
