Description

The Quantum Spin Liquid is a novel magnetic ground state, characterized by quantum entanglement without long range magnetic order. Kagome lattice Heisenberg antiferromagnet is a prime candidate of quantum spin liquid owing to highly frustrated spin ½’s arranged on a corner sharing triangle geometry. We report 19F NMR investigation of a series of “barlowite” kagome material Zn1-xCu3+x(OD)6FBr with x ~ 0.05, 0.5, and 1 based on the inverse Laplace transform analysis on the spin-lattice relaxation rate 1/T1.
