Slow crystalline electric field fluctuations in the Kondo lattice SmB
M. Carlone, J. C. Souza, J. Sichelschmidt +7
This work reports on the temperature dependence of the electron spin resonance (ESR) of Gd-doped SmB single crystals at X- and Q-band microwave frequencies in differen…
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…
Microscopic probe of magnetic polarons in antiferromagnetic EuInSb
J. C. Souza, S. M. Thomas, E. D. Bauer +4
Colossal magnetoresistance (CMR) emerges from intertwined spin and charge degrees of freedom in the form of ferromagnetic clusters also known as trapped magnetic polarons. As a res…
Surface excitations relaxation in the Kondo insulator SmGdB
J. C. Souza, M. König, M. V. Ale Crivillero +7
The interplay between non-trivial topological states of matter and strong electronic correlations is one of the most compelling open questions in condensed matter physics. Due to e…
Systematic manipulation of the surface conductivity of SmB
M. Victoria Ale Crivillero, M. König, J. C. Souza +5
We show that the resistivity plateau of SmB at low temperature, typically taken as a hallmark of its conducting surface state, can systematically be influenced by different sur…
Quantum Criticality in a Layered Iridate
Kousik Samanta, Jean C. Souza, Danilo Rigitano +3
Iridates provide a fertile ground to investigate correlated electrons in the presence of strong spin-orbit coupling. Bringing these systems to the proximity of a metal-insulator qu…
