| 英文摘要 | We report a comprehensive investigation of the frustrated magnetism on the delafossite oxides, alpha-CrOOH and alpha-CrOOD, which experimentally realize the S = 3/2 nearly-Heisenberg antiferromagnetic (J(1) > 0) model on a triangular lattice with weak single-ion anisotropy (D). The electron spin resonance (ESR), neutron scattering, and specific heat (C-m) measurements on both alpha-CrOOH and alpha-CrOOD consistently indicate that the long-range 120 degrees Neel order is significantly suppressed and both systems are in the vicinity of a spin-liquid phase with C-m similar to T-2 at low temperatures. The strength of D is quantitatively determined from fitting the high-temperature ESR linewidth and magnetic susceptibility, and its minus sign (D < 0, easy-axis type) is suggested by the low-energy (E <= 2 meV) spin excitations. This easy-axis anisotropy (D/J(1) similar to -5%) competes with the 120 degrees Neel order and thus enhances the quantum spin fluctuations at low temperatures. |
