Crystal-Field--Driven Magnetoelectricity in the Triangular Quantum Magnet CeMgAl${}_{11}$O${}_{19}$

Sonu Kumar, Gaël Bastien, Maxim Savinov +6

We report dielectric and magnetoelectric studies of single-crystalline \ce{CeMgAl11O19}, a Kramers triangular magnet embedded in a polarizable hexaaluminate lattice. In zero magnet…
