Structural, Thermodynamic, and Magnetic Investigations of Ti<sup>3+</sup>-Based Kagome Antiferromagnets.

Abstract

The pursuit of quantum spin liquid (QSL) states has brought intense focus to kagome antiferromagnets (AFMs), where the two-dimensional network of corner-sharing triangles produces strong geometric frustration that suppresses conventional magnetic order, providing an ideal platform to realize and explore exotic quantum states. Recently, several new Kagome compounds Cs8AB3Ti12F48 (A = Rb and Li, B = K and Na) were discovered, where Ti3+ (3d1, s = ½) ions are surrounded by six F- ligands and form modulated kagome lattices. In this talk, we will present our experimental studies, including joint X-ray and neutron single-crystal structural refinement, bulk magnetization, and low temperature specific heat measurements, performed on single crystals of Cs8RbK3Ti12F48, Cs8LiK3Ti12F48, and Cs8LiNa3Ti12F48.
