The quantum Kagome magnets have been intensively investigated for studying the exotic states, including quantum spin liquid (QSL), superconductivity, topological phases, etc. Our research has focused on different Kagome magnets and scoped in Kagome ferromagnet α-Cu₃Mg(OH)6Br₂, antiferromagnet YCu₃(OH)6Cl₃ and quantum spin liquid candidate Zn-Barlowite. In α-Cu₃Mg(OH)6Br₂, we have observed Bose—Einstein condensation of magnons with applied magnetic field along the c axis and found that the out-of-plane Dzyaloshinskii Moriya (DM) interaction plays a central role in controlling the U(1) symmetry. YCu₃(OH)6Cl₃ displays 'q=0' type antiferromagnetic order, while substituting Y3+ by lanthanides Ln3+ (Ln = Nd-Dy), the Ln3+ dominates the low temperature magnetic behaviors but shows little impact on the magnetic order of Kagome lattice of Cu2+. Two magnetic phase transitions have been observed in Y₃Cu9(OH)19Cl8 and related analogous compounds with distorted Kagome lattice of Cu2+: low temperature order approximately at 2 ~ 3 K, and another phase transition around 25 ~ 30 K. For Zn-Barlowite, when Zn content x is larger than 0.6, the ferromagnetic order can be totally suppressed, and Zn0.8Cu3.2(OH)6FBr crystals in our experiments remain in QSL candidate scenario due to absence of magnetic order down to 350 mK. In the comparative Raman experiments, we observed magnetic excitations of spinon-pairs and magnons in the QSL candidate Zn0.8Cu3.2(OH)6FBr and antiferromagnetically- ordered compound EuCu3(OH)6Cl3, respectively. For Zn0.8Cu3.2(OH)6FBr, we have identified one-pair spinons in the low-temperature Raman spectra.
