| 520 | _ | _ | |a Structurally, the mineral clinoatacamite Cu$_2$Cl(OH)$_3$ is closely related to the kagome material herbertsmithite Zn$_3$CuCl$_2$(OH)$_6$. In clinoatacamite, however, the kagome motif of Cu sites is embedded into a low-symmetry crystal structure, which causes a distortion of the kagome plane as well as different site symmetries for the kagome Cu sites. Unlike the quantum spin liquid candidate herbertsmithite, clinoatacamite undergoes a magnetic transition at 18.1 K. Its magnetic ground states have remained inconclusive to date. Here, we will revisit the magnetic properties using single-crystalline material. We will first demonstrate using density-functional theory that the dominant magnetic exchange couplings in this material form non-uniform antiferromagnetic kagome layers of Cu sites with weak ferromagnetic couplings to the interlayer Cu site. Further, we have characterized clinoatacamite by means of thermodynamic measurement techniques, muon spin rotation/relaxation as well as neutron diffraction. We reveal a zero-field magnetic phase diagram which is far more complex than previously anticipated. We discuss our data within a scenario of competing order parameters on the inequivalent Cu sites. |
