Synergistic doping and stabilization of magnetically tunable LnTi(Sb,Sn) (Ln:Ce--Gd) kagome metals
Brenden R. Ortiz, Ramakanta Chapai, German Samolyuk +9
Here we present our synthesis and characterization of the LnTi(Sb,Sn) (Ln: Ce, Pr, Nd, Sm, Gd) family of cleavable kagome metals. While these materials are isostructural to…
Interleaved bond frustration in a triangular lattice antiferromagnet
S. J. Gomez Alvarado, J. R. Chamorro, D. Rout +14
Frustration of long-range order via lattice geometries serves to amplify fluctuations of the order parameter and generate unconventional ground states that are highly sensitive to…
V NMR evidence for interlayer-modulated charge order and a first-order low-temperature transition in CsVSb
Xiaoling Wang, Arneil P. Reyes, Hrishit Banerjee +3
Charge order in the kagome superconductor CsVSb exhibits a complex three-dimensional organization and intermediate-temperature anomalies whose bulk character has remained u…
Enhanced Neel temperature and unusual thermal expansion in flux-grown FeCrAs crystals
Michael A. McGuire, Matthew S. Cook, Brenden R. Ortiz +2
We report results from our experimental investigation of the distorted-kagome compound FeCrAs. For this work, we developed a procedure using tin metal as a flux to produce needleli…
Isolated spin ladders in LnTiSb (Ln:La-Nd) metals
Brenden R. Ortiz, Heda Zhang, Karolina Gornicka +4
Here we present the discovery and characterization of a series of antimonides LnTiSb (Ln: La--Nd) which exhibit well-isolated, rare-earth spin ladders. We disc…
Interplay of - and -states in RbTiBi and CsTiBi flat-band kagome metals
M. Wenzel, E. Uykur, A. A. Tsirlin +4
Shifting the Fermi level of the celebrated (135) compounds into proximity of flat bands strongly enhances electronic correlations and severely affects the formation of de…
