Unravelling the magnetic phase in the buckled honeycomb lattices R2Te4O11 (R = Gd, Er and Nd)

Abstract: Low-dimensional frustrated quantum magnet has been garnered significant attention from the condensed matter research community, due to its diverse range of intriguing magnetic ground states. In these systems, frustration plays a key role in giving rise to exotic magnetic phases, which arises from geometric constraints, lattice arrangements, or competing exchange interactions. Some of the well-known low-dimensional frustrated quantum magnets include square, triangular, Kagome and honeycomb layered lattices, along with Shastry-Sutherland lattice, where the arrangement of magnetic moments cannot simultaneously satisfy all interactions, thus preventing the system from settling into a trivial ground state. Among these, buckled honeycomb lattice is another interesting quasi-2D lattice which comprises of bilayer triangular lattice, that are arranged in a manner that it forms a honeycomb. In this respect, an interesting series, R2Te4O11 (RTO), where R = Gd, Er and Nd) is need to explore. In RTO, R3+ ions form two set of isosceles triangles sublattice that are coupled in a manner which forms buckled honeycomb lattice. The distorted nature of triangular lattice leads to competing interaction and interlayer coupling further enhances the frustration in this system, which results to intriguing quantum magnetic phases. Therefore, µSR study will be helpful to unravel the underlying physics of these phenomena at low T.
