The quantum kagome magnets have been intensively investigated for study the exotic states, including quantum spin liquid (QSL), superconductivity, topological phases. Our research has focused on different kagome magnets and scoped in inplane ferromagnetism, ‘q=0’ type antiferromagnetism and absence of magnetic order. In α-Cu3Mg(OH)6Br2, we have observed Bose–Einstein condensation of magnons with field along c axis, and found that the out-of-plane Dzyaloshinskii Moriya (DM) interaction plays a center role in controlling the U(1) symmetry. YCu3(OH)6Cl3 performs ‘q=0’ type antiferromagnetic order, with substituting Y by lanthanides Ln3+ (Ln = Nd-Dy), the Ln3+ has dominated the low temperature magnetic behaviors but shows little impact on the magnetic order of kagome lattice of Cu2+. For Y3Cu9(OH)19Cl8 and related analogous compounds, we have observed two magnetic order: one is in near 2 K and another magnetic order is around 25-30 K. For Znbarlowite, when Zn content x is larger than 0.6, the ferromagnetic order can be totally suppressed and Zn0.8Cu3.2(OH)6FBr is a new QSL candidate. In the comparative Raman experiments, we observed deconfinement and confinement in the QSL candidate Zn0.8Cu3.2(OH)6FBr and antiferromagnetic-order compounds EuCu3(OH)6Cl3, respectively. For Zn0.8Cu3.2(OH)6FBr, we have obtained lowtemperature profile of Raman spectra for one-pair spinons.
