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

G. Bastien, A. Eliáš, A. Eliᚠ+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…
