Exotic quantum spin liquid (QSL) is formed with such hypothetic particles as fermionic spinons carrying spin 1/2 and no charge. A search for the materials is a challenge for a condensed matter physics. The key features of our findings are the presence of spin-charge separation and QSL formed with itinerant heavy spinons. These findings are in a good agreement with experimental data and allow us to detect the behavior of QSL as that observed in heavy fermion metals and ²D ³He.
