TbTi₃Bi₄ (Terbium Titanium Bismuthide)

A layered RTi₃Bi₄ kagome magnet in which Ti kagome nets coexist with a Tb sublattice arranged in chains. The Tb³⁺ ions carry large 4f moments with strong Ising-like magnetic anisotropy, producing highly anisotropic magnetic order coupled to the kagome flat bands, Dirac crossings, and van Hove singularities of the Ti network. The strong single-ion anisotropy and field-tunable metamagnetic transitions make TbTi₃Bi₄ a prominent platform for studying anisotropic magnetic kagome metals and topological magnetotransport.

Sample specifications: Individual crystals measure approximately 2–3 mm, with a purity of up to 99.9999% (6N), and multiple high-quality single-crystal pieces included in each package.

Exfoliation: Difficult — strong interlayer bonding; mechanical exfoliation typically yields thick flakes, and ultrathin flakes are challenging to isolate.

Growth method: Flux growth.
