Anisotropic Lattice Compression and Pressure-Induced Electronic Phase Transitions in SrIrO
K. Samanta, R. Tartaglia, U. F. Kaneko +2
The crystal lattice of SrIrO is investigated with synchrotron X-ray powder diffraction under hydrostatic pressures up to GPa and temperatures down to K. The tet…
Crystal structure, cobalt and iron speciation and oxygen non-stoichiometry of La0.6Sr0.4Co1-yFeyO3-d nanorods for IT-SOFC cathodes
Augusto E. Mejía Gómez, Joaquín Sacanell, Cristián Huck-Iriart +7
Single-phased La0.6Sr0.4Co1-yFeyO3-d (y = 0.2, 0.5, 0.8) nanorods exhibiting the rhombohedral perovskite-type phase were synthesized by a pore-wetting technique. We studied their c…
Entropy bounds and nonlinear electrodynamics
F. T. Falciano, M. L. Peñafiel, Santiago Esteban Perez Bergliaffa
Bekenstein's inequality sets a bound on the entropy of a charged macroscopic body. Such a bound is understood as a universal relation between physical quantities and fundamental co…
Toward Realistic Amorphous Topological Insulators
Marcio Costa, Gabriel R. Schleder, Marco Buongiorno Nardelli +2
The topological properties of materials are, until now, associated with the features of their crystalline structure, although translational symmetry is not an explicit requirement…
Role of quantum confinement and interlayer coupling in CrI-graphene magnetic tunnel junctions
Jonathan J. Heath, Marcio Costa, Marco Buongiorno-Nardelli +1
Recent demonstrations of magnetic ordering and spin transport in two-dimensional heterostructures have opened research venues in these material systems. In order to control and enh…
The zero-field-cooled exchange bias effect in phase-segregated LaACoMnO (A = Ba, Ca, Sr; x = 0, 0.5)
L. T. Coutrim, D. Rigitano, C. Macchiutti +9
In the zero-field-cooled exchange bias (ZEB) effect the unidirectional magnetic anisotropy is set at low temperatures even when the system is cooled in the absence of external magn…
Ultrathin SnTe films as a route towards all-in-one spintronics devices
Jagoda Sławińska, Frank T. Cerasoli, Priya Gopal +3
Spin transistors based on a semiconducting channel attached to ferromagnetic electrodes suffer from fast spin decay and extremely low spin injection/detection efficiencies. Here, w…
Phase Transition and Electronic Structure Investigation of MoS-rGO Nanocomposite Decorated with AuNPs
Yunier Garcia-Basabe, Gabriela F. Peixoto, Daniel Grasseschi +5
In this work a simple approach to transform MoS from its metallic (1T' to semiconductor 2H) character via gold nanoparticle surface decoration of a MoS graphene oxide (rGO)…
Magnetic structure and magnetoelastic coupling of GdNiSi3 and TbNiSi3
R. Tartaglia, F. R. Arantes, C. W. Galdino +4
The series of intermetallic compounds NiSi ( = rare earth) shows interesting magnetic properties evolving with and metamagnetic transitions under applied magnetic fie…
Approximate expression for the ground-state energy of the two- and three-dimensional Hubbard model at arbitrary filling obtained from dimensional scaling
Luana N. O. Vilela, Klaus Capelle, Luiz N. Oliveira +1
We generalize the linear discrete dimensional scaling approach for the repulsive Hubbard model to obtain a nonlinear scaling relation that yields accurate approximations to the gro…
Pressure-tuning of the electrical-transport properties in the Weyl semimetal TaP
M. Besser, R. D. dos Reis, F. -R. Fan +5
We investigated the pressure evolution of the electrical transport in the almost compensated Weyl semimetal TaP. In addition, we obtained information on the modifications of the Fe…
The distribution of oxygen at the Ni81Fe19/Ta interface
T. J. A. Mori, R. D. D. Pace, W. H. Flores +3
The knowledge of how oxygen atoms are distributed at a magnetic-metal / oxide, or magnetic-metal / non-magnetic-metal interface, can be an useful tool to optimize device production…
Zeeman-type spin splitting in non-magnetic three-dimensional compounds: Materials prediction and electrical control
Carlos Mera Acosta, Adalberto Fazzio, Gustavo M. Dalpian
Despite its potential for device application, the non-magnetic Zeeman effect has only been predicted and observed in two-dimensional compounds. We demonstrate that non-centrosymmet…
