Hyperfine Couplings as a Probe of Orbital Anisotropy in Heavy Fermion Materials
P. Menegasso, J. C. Souza, I. Vinograd +5
The transferred hyperfine interaction between nuclear and electron spins in an heavy fermion material depends on the hybridization between the -electron orbitals and those surro…
Metallic islands in the Kondo insulator SmB
J. C. Souza, P. F. S. Rosa, J. Sichelschmidt +7
The predicted interplay between Kondo physics and non-trivial topology in SmB has stimulated many experimental reports, some of which are in apparent contradiction. The origi…
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…
Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…
Revisiting the Possible 4f7 5d1 Ground State of Gd Impurities in SmB6 by Electron Spin Resonance
J. C. Souza, P. F. S. Rosa, U. Burkhardt +5
The search for topological states in strongly correlated electron systems has renewed the interest in the Kondo insulator SmB6. One of the most intriguing previous results was an a…
