Triangular lattices with antiferromagnetic nearest neighbour exchange interactions are some of the most popular examples of geometrically frustrated systems. Recently, YbMgGaO₄ has been considered as a potential quantum spin liquid candidate, where the magnetic Yb³⁺ ions are forming a quasi two dimensional triangular lattice while Mg²⁺/Ga³⁺ are randomly mixed between the Yb layers. The variation of exchange interactions produced by the disordered ions and the frustration from the triangular planes are expected to produce the spin liquid ground state. By replacing Yb with Er, different interaction strengths of J₁ and J₂ are expected, resulting in an interesting unknown ground state. Here, we will show our results of single crystal growth of ErMgGaO₄ and its magnetic properties.
