abstract = {We report on comprehensive results identifying the ground
state of a triangular-lattice structuredYbZnGaO4 as a spin
glass, including no long-range magnetic order, prominent
broad excitation continua,and the absence of magnetic
thermal conductivity. More crucially, from the
ultralow-temperature acsusceptibility measurements, we
unambiguously observe frequency-dependent peaks around 0.1
K,indicating the spin-glass ground state. We suggest this
conclusion holds also for its sister compoundYbMgGaO4, which
is confirmed by the observation of spin freezing at low
temperatures. We considerdisorder and frustration to be the
main driving force for the spin-glass phase.},
