Magnetic devil's staircase in UAgBi
G. S. Freitas, K. Kirchner, C. Girod +10
Materials characterized by competing interactions often exhibit a large number of nearly degenerate periodic states. Here we show that layered UAgBi hosts a cascade of field- a…
Magnetization Plateaus in the Spin-Orbit Coupled Bilayer Triangular Lattice Antiferromagnet Rb2Co2(SeO3)3
Shengzhi Zhang, Gabriel Silva Freitas, Vivien S. Zapf +8
Geometric frustration among competing spin exchanges can give rise to novel quantum phases by enhancing fluctuations that drive magnetic systems beyond the classical regime. We inv…
YNiSn: A candidate Dirac semimetal
G. S. Freitas, C. Kaufmann Ribeiro, F. B. Carneiro +16
We report the synthesis and physical properties of the new compound YNiSn, which crystallizes in the orthorhombic \textit{Cmcm} structure. The material exhibits semimetallic be…
Hole doping and electronic correlations in Cr-substituted BaFeAs
Marli R. Cantarino, K. R. Pakuszewski, Björn Salzmann +7
Superconductivity (SC) is absent in Cr-substituted BaFeAs (CrBFA), a well-established but poorly understood topic. Additionally, the suppression of the spin density wav…
Orbital localization and the role of the Fe and As orbitals in BaFeAs probed by XANES
A. G. de Figueiredo, M. R. Cantarino, W. R. da Silva Neto +9
The polarization dependence of the near edge x-ray absorption spectroscopy (XANES) is an element specific probe to the real-space distribution of the density of unoccupied states i…
Tuning the crystalline electric field and magnetic anisotropy along the CeCuBiSb series
G. S. Freitas, M. M. Piva, R. Grossi +8
We have performed X-ray powder diffraction, magnetization, electrical resistivity, heat capacity and inelastic neutron scattering (INS) to investigate the physical properties of th…
Electronic and magnetic properties of stoichiometric CeAuBi
M. M. Piva, R. Tartaglia, G. S. Freitas +13
We report the electronic and magnetic properties of stoichiometric CeAuBi single crystals. At ambient pressure, CeAuBi orders antiferromagnetically below a Néel tempera…
