Magnetic Structures on Kagome Spin Liquid Compound Cu4(OD)6FBr and Cu3Zn(OD)6FBr

PID

A two-dimensional kagome antiferromagnet can achieve a spin-liquid ground state due to strong quantum uctuations and geometrical frustrations, but the topological nature of its ground state and low-energy excitations is still controversial. We have successfully synthesized deuterated Cu4(OD)6FBr and Cu3Zn(OD)6FBr, both of which have kagome layers of Cu2+ that antiferromagnetically coupled. It has been shown that Cu4(OD)6FBr shows a magnetic transition at about 15 K whereas our recent measurement on Cu3Zn(OD)6FBr show no phase transition down to 50 mK. Therefore, these samples provide us a great opportunity to study the quantum spin liquid physics in kagome lattice. Here we propose to study the magnetic and nuclear structures of both samples on E9.
