Type-I superconductivity in a quasi-2D topologically nontrivial YbBi $_{2}$

Karolina Górnicka, Sudip Malick, Joanna Bławat +13

Intrinsic superconductivity in stoichiometric materials with nontrivial electronic topology remains uncommon, limiting opportunities to investigate how these two phenomena coexist…

Fermiology of the kagome compound LuNb6Sn6 probed by de Haas-van Alphen oscillations

Tucker Beekmann, Caue Kaufmann Ribeiro, Kyryl Shtefiienko +4

We report a detailed de Haas-van Alphen (dHvA) study of the recently discovered kagome metal LuNb6Sn6 using torque magnetometry, magnetization, and heat-capacity measurements. Temp…

Recent progress on liquid transport growth of quantum materials

Jiaqiang Yan, Brenden Ortiz

Liquid transport growth (LTG) is a horizontal flux growth technique that is closely analogous to chemical vapor transport, with the key distinction that a molten flux rather than a…

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…

Interplay between charge correlations and superconductivity across the superconducting domes of CsV $_{3}$ Sb $_{5 - x}$ Sn $_{x}$

Andrea N. Capa Salinas, Brenden R. Ortiz, Steven J. Gomez Alvarado +9

The kagome metal CsV $_{3}$ Sb $_{5}$ shows an unconventional interplay between charge density wave (CDW) order and superconductivity. Tuning the band filling is known to rapidly suppress…

Anisotropic magnetism of polymorphic ErAl3

Karolina Gornicka, Brenden R. Ortiz, Andrew D. Christianson +1

ErAl $_{3}$ can form in either a trigonal ( $α$ ) or cubic ( $β$ ) polymorph and this paper investigates the physical properties of these polymorphs through characterizations of single cr…

Impact of charge-density-wave pattern on the superconducting gap in V-based kagome superconductors

T. Nagashima, K. Ishihara, Y. Yamakawa +12

Kagome metals $A$ V $_{3}$ Sb $_{5}$ ( $A =$ K, Rb, Cs) provide a compelling platform to explore the interplay between superconductivity (SC) and charge-density-wave (CDW) orders. While dist…

Frustrated Ising charge correlations in the kagome metal ScV $_{6}$ Sn $_{6}$

S. J. Gomez Alvarado, G. Pokharel, B. R. Ortiz +4

Here we resolve the real-space nature of the high-temperature, short-range charge correlations in the kagome metal ScV $_{6}$ Sn $_{6}$ . Diffuse scattering appears along a frustrated wave…

MnRhBi3: A Cleavable Antiferromagnetic Metal

Eleanor M. Clements, Dmitry Ovchinnikov, Parul R. Raghuvanshi +10

Cleavable metallic antiferromagnets may be of use for low-dissipation spintronic devices; however, few are currently known. Here we present orthorhombic MnRhBi3 as one such compoun…
