 trong></p>  <p>The Kitaev model has become extremely popular in the field 
 of quantum spin liquid (QSL) materials\, as it is an exactly solvable mode
 l for the honeycomb lattice that possesses the quantum spin liquid state a
 s a possible ground state for a material with the right balance of exchang
 e interactions. However\, the Kitaev spin liquid remains until now elusive
 \, as this state is fragile and destroyed by perturbations\, such as small
  admixture of a conventional Heisenberg coupling caused by direct overlap 
 of the d orbitals and long-range couplings\, unavoidable in weakly localiz
 ed 5d- and 4d-electron systems with the spatially extended d wave function
 s. As an alternative\, 3d systems with more compact d orbitals have been p
 roposed\, among them\, several cobaltates.</p>  <p>In this talk\, I will p
 resent recent results on high-quality single crystals of the QSL candidate
  Na3Co2SbO6\, characterized by thermodynamic methods. The large anisotropy
  of this antiferromagnetic material and the rich variety of field-induced 
 phases\, together with theoretical predictions pointing to a possible stra
 in/pressure-driven Kitaev spin liquid phase\, make it a stimulating playgr
 ound for the study of Kitaev physics.</p>  <p><strong>BigBlueButton</stron
