Induced quantum magnetism on a triangular lattice of non-Kramers ions in PrMgAl11O19
Original language description
We report the magnetic properties of the quantum triangular lattice antiferromagnet PrMgAl11O19 through magnetization and specific-heat measurements. Strong magnetic anisotropy indicates the realization of an Ising-like magnetism in PrMgAl11O19 single crystal while no long-range magnetic ordering is realized down to 0.4 K. The splitting of the low-lying quasidoublet of the non-Kramers ion Pr3+ into two singlets, suggested by experimental data, is consistent with an effective pseudospin-1/2 scenario. Single-crystal x-ray diffraction shows the repartition of Pr3+ ions between two slightly different positions in their oxygen cage, and specific-heat measurements consistently show a double-Schottky anomaly, attributed to excitations between the two singlets of the low-lying quasidoublet from the two distinct sites.
