Anisotropic magnetism and Kondo-lattice behavior in the frustrated antiferromagnet Ce3MgBi5

Karolina Gornicka, Brenden R. Ortiz, Matthew S. Cook +3

We report the synthesis and physical characterization of single-crystalline Ce3MgBi5, a previously unexplored member of the Ce3MPn5 family. This compound crystallizes in the hexago…

Observation of the Magnus Nonlinear Hall effect from Chiral Weyl Monopoles

Heda Zhang, Nikolai Peshcherenko, Ning Mao +4

The nonlinear Hall effect (NLHE) connects crystalline symmetry to quantum geometry, offering a probe of band topology beyond linear transport. While most studies have focused on th…

Isolated spin ladders in Ln $_{2}$ Ti $_{9}$ Sb $_{11}$ (Ln:La-Nd) metals

Brenden R. Ortiz, Heda Zhang, Karolina Gornicka +4

Here we present the discovery and characterization of a series of antimonides Ln $_{2}$ Ti $_{9}$ Sb $_{11}$ (Ln: La--Nd) which exhibit well-isolated, $n = 2$ rare-earth spin ladders. We disc…

Evidence of chiral fermion edge modes through geometric engineering of thermal Hall in $I^\pm$ -RuCl $_{3}$

Heda Zhang, Gabor B. Halasz, Sujoy Ghosh +5

The experimental observation of half-integer-quantized thermal Hall conductivity in the Kitaev candidate material $I^\pm$ -RuCl $_{3}$ has served as smoking-gun signature of non-Abelian a…

Stability frontiers in the AM $_{6}$ X $_{6}$ kagome metals: The LnNb $_{6}$ Sn $_{6}$ (Ln:Ce-Lu,Y) family and density-wave transition in LuNb $_{6}$ Sn $_{6}$

Brenden R. Ortiz, William R. Meier, Ganesh Pokharel +16

The kagome motif is a versatile platform for condensed matter physics, hosting rich interactions between magnetic, electronic, and structural degrees of freedom. In recent years, t…
