This paper presents thermodynamic and muon spin relaxation measurements, along with ab initio density functional theory and exact diagonalization results, on the frustrated antiferromagnet Li₄CuTeO₆. The study finds no long-range magnetic ordering or spin freezing down to 45 mK, despite strong antiferromagnetic interactions. Data collapse analysis of magnetization and specific heat suggests a disorder-driven correlated and dynamic ground state, consistent with a random-singlets spin liquid.
