The effects of Zn doping on magnetic properties of Cu$_{\mathrm{\mathbf{3}}}$\textbf{Bi(SeO}$_{\mathrm{\mathbf{3}}}$\textbf{)}$_{\mathrm{\mathbf{2}}}$\textbf{O}$_{\mathrm{\mathbf{2}}}$\textbf{Cl}

Recently, layered spin-frustrated Cu$_{\mathrm{3}}$Bi(SeO$_{\mathrm{3}})_{\mathrm{2}}$O$_{\mathrm{2}}$Cl has received considerable research attention due to its unusual magnetic properties. Two inequivalent Cu$^{\mathrm{2+\thinspace }}$ions form a pseudo-kagome lattice that invokes spin frustration and anisotropic magnetic properties. In this study, the influence of Zn doping on the complex magnetic properties has been explored. Polycrystalline (Cu$_{\mathrm{1-x}}$Zn$_{\mathrm{x}})$Bi(SeO$_{\mathrm{3}})_{\mathrm{2}}$O$_{\mathrm{2}}$Cl (0 x 0.5) samples were synthesized using solid-state reaction and characterized by X-ray diffraction and magnetic measurements. The Zn doping strongly modulates the magnetic ground state of the system. The antiferromagnetic transition temperature $T_{N} =$ 24 K and magnetic field-induced hysteresis observed for x $=$ 0 at low field are systematically shifted to lower temperature and reduced with Zn doping. These results can illustrate the insight of the occurrence of field-induced spin-flip type multiferroics in Cu$_{\mathrm{3}}$Bi(SeO$_{\mathrm{3}})_{\mathrm{2}}$O$_{\mathrm{2}}$Cl.
