Effects of external pressure on the narrow gap semiconductor CeCdAs
M. M. Piva, L. Xiang, J. D. Thompson +4
Here we report the magnetic and electronic properties of recently discovered CeCdAs. At ambient pressure, CeCdAs presents a semiconducting behav…
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…
The planar triangular magnet AgCrSe: magnetic frustration, short range correlations, and field tuned anisotropic cycloidal magnetic order
M. Baenitz, M. M. Piva, S. Luther +25
Our studies evidence an anisotropic magnetic order below ~K. Susceptibility data in small fields of about 1~T reveal an antiferromagnetic (AFM) order for , whe…
Robust narrow-gap semiconducting behavior in square-net LaCdAs
Mario M. Piva, Marein C. Rahn, Sean M. Thomas +6
ABSTRACT: Narrow-gap semiconductors are sought-after materials due to their potential for long-wavelength detectors, thermoelectrics, and more recently non-trivial topology. Here w…
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…
