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…
Spin density wave and van Hove singularity in the kagome metal CeTi3Bi4
Pyeongjae Park, Brenden R. Ortiz, Milo Sprague +15
Kagome metals with van Hove singularities near the Fermi level can host intriguing quantum phenomena such as chiral loop currents, electronic nematicity, and unconventional superco…
Unusual magnetic and transport properties in HoMnSn kagome magnet
Firoza Kabir, Randall Filippone, Gyanendra Dhakal +11
With intricate lattice structures, kagome materials are an excellent platform to study various fascinating topological quantum states. In particular, kagome materials, revealing la…
Magnetic, transport, and thermal properties of -phase UZr
Xiaxin Ding, Tiankai Yao, Lyuwen Fu +7
Alloys of hexagonal -phase UZr have been synthesized and studied by means of heat capacity, magnetic susceptibility, magnetization, electrical resistivity, magnetoresistance…
A new form of (unexpected) Dirac fermions in the strongly-correlated cerium monopnictides
Nasser Alidoust, A. Alexandradinata, Su-Yang Xu +14
Discovering Dirac fermions with novel properties has become an important front in condensed matter and materials sciences. Here, we report the observation of unusual Dirac fermion…
Electron-hole compensation effect between topologically trivial electrons and nontrivial holes in NbAs
Yongkang Luo, N. J. Ghimire, M. Wartenbe +7
Via angular Shubnikov-de Hass (SdH) quantum oscillations measurements, we determine the Fermi surface topology of NbAs, a Weyl semimetal candidate. The SdH oscillations consist of…
