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…
Fermi Surface Topology and Magneto-transport Properties of Superconducting PdBiSe
Ramakanta Chapai, Gordon Peterson, M. P. Smylie +5
PdBiSe is a rare realization of a superconducting metal with a non-zero topological invariant. We report the growth of high-quality single crystals of layered Pd$…
Magnetic Breakdown and Topology in the Kagome Superconductor CsV3Sb5 under High Magnetic Field
Ramakanta Chapai, Maxime Leroux, Vincent Oliviero +7
The recently discovered layered Kagome metals of composition AV3Sb5 (A = K, Rb, Cs) exhibit a complex interplay among superconductivity, charge density wave order, topologically no…
Fermions and bosons in nonsymmorphic PdSb2 with sixfold degeneracy
Ramakanta Chapai, Yating Jia, W. A. Shelton +6
PdSb2 is a candidate for hosting 6-fold-degenerate exotic fermions (beyond Dirac and Weyl fermions).The nontrivial band crossing protected by the nonsymmorphic symmetry plays a cru…
Structure-Property Relationship in Layered BaMn2Sb2 and Ba2Mn3Sb2O2
Qiang Zhang, Zhenyu Diao, Huibo Cao +5
Layered transition-metal compounds have received great attention owing to their novel physical properties. Here, we present the structural, electronic, thermal, and magnetic proper…
