Constraining the parameter space of triangular lattice compound YbZnGaO4

In the last few years Yb- based triangular lattice antiferromagnets emerged as promising quantum spin liquid candidates, and subsequently their ground states have been the subject of ardent debates. Though many experimental and theoretical studies have been devoted to investigating the magnetic properties of these systems at very low temperatures, and exploring a range of possible explanations for the observed spin liquid-like phenomena, a definitive description remains elusive mainly due to chemical disorder. In this talk we discuss further advances in determining the parameter space of YbZnGaO4, using a wide range of experimental techniques and comparisons to theory.
