Thermodynamic, dynamic and transport properties of quantum spin liquid in herbertsmithite from experimental and theoretical point of view

In our review we focus on the quantum spin liquid, defining the thermodynamic, transport and relaxation properties of geometrically frustrated magnets (insulators) represented by herbertsmithite $\mathrm{Z}\mathrm{n}\mathrm{C}{\mathrm{u}}_3(\mathrm{O}\mathrm{H}{)}_6\mathrm{C}{\mathrm{l}}_2$.
