Crystal growth and magnetic properties of ErMgGaO<sub>4</sub>
ORAL
Abstract
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.
