Evidence for field induced quantum spin liquid behavior in a spin-1/2 honeycomb magnet
One of the most important issues in modern condensed matter physics is the
realization of fractionalized excitations, such as the Majorana excitations in
the Kitaev quantum spin liquid. To this aim, the 3d-based Kitaev material
Na2Co2TeO6 is a promising candidate whose magnetic phase diagram of B // a*
contains a field-induced intermediate magnetically disordered phase within 7.5
T < |B| < 10 T. The experimental observations, including the restoration of the
crystalline point group symmetry in the angle-dependent torque and the
coexisting magnon excitations and spinon-continuum in the inelastic neutron
scattering spectrum, provide strong evidence that this disordered phase is a
field induced quantum spin liquid with partially polarized spins. Our
variational Monte Carlo simulation with the effective
K-J1-{\Gamma}-{\Gamma}'-J3 model reproduces the experimental data and further
supports this conclusion.
