Quantum oscillations and Dirac dispersion in tunable kagome lattice Lu $_{1 - y}$ Y $_{y}$ (Nb $_{1 - x}$ Ta $_{x}$ ) $_{6}$ Sn $_{6}$

Keenan Avers, Phineas Sobel, Lochlan Joyce +6

Kagome lattice crystal systems present interesting symmetry-protected band structure features such as flat bands, van Hove singularities, and linearly dispersing Dirac/Weyl points…

Complex single-site magnetism and magnetotransport in single-crystalline Gd $_{2}$ AlSi $_{3}$

Ram Kumar, Shanta R. Saha, Jarryd Horn +8

We present a detailed investigation of single-crystal samples of the magnetic compound Gd $_{2}$ AlSi $_{3}$ , which crystallizes in the $I^\pm$ -ThSi $_{2}$ type tetragonal structure. We rep…

Dilute Paramagnetism and Non-Trivial Topology in Quasicrystal Approximant Fe $_{4}$ Al $_{13}$

Keenan E. Avers, Jarryd A. Horn, Ram Kumar +5

A very fundamental property of both weakly and strongly interacting materials is the nature of its magnetic response. In this work we detail the growth of crystals of the quasicrys…
