Probing 4f Crystal-Field Excitations and Magnetic Anisotropy in the Topological Magnet NdTi?Bi? with MERLIN Neutron Spectroscopy

Abstract: The LnTi3Bi4 [Ln: Rare earth element] family of compounds is structurally characterized by a slightly distorted Ti double kagome layer, which is sandwiched between Ln Bi double layers. In this configuration, the rare-earth (Ln) atoms form highly anisotropic quasi-one-dimensional zigzag chains. The primary appeal of this family lies in its highly tunable magnetism, which can be precisely controlled through rare-earth engineering to adjust the magnetic state from nonmagnetic to ferromagnetic (FM) or antiferromagnetic (AFM). NdTi3Bi4 is part of this newly discovered 2D kagome lattice material family. NdTi3Bi4 exhibits a complex magnetic transition at Tc = 8.8 K., Here we propose to investigate in detail magnetic excitations, spin wave and crystal field (CEF) of NdTi3Bi4 using single inelastic neutron scattering measurements on MERLIN. The results of the proposed study are important to understand the complex magnetism and strength on exchange parameters of NdTi3Bi4.
