Experimental observation of metallic states with different dimensionality in a quasi-1D charge density wave compound
P. Rezende-Gonçalves, M. Thees, J. Rojas Castillo +14
TaTe is a quasi-1D tetrachalcogenide that exhibits a CDW instability caused by a periodic lattice distortion. Recently, pressure-induced superconductivity has been achieved in…
Direct detection of induced magnetic moment and efficient spin-to-charge conversion in graphene/ferromagnetic structures
J. B. S. Mendes, O. Alves Santos, T. Chagas +7
This article shows that the spin-to-charge current conversion in single-layer graphene (SLG) by means of the inverse Rashba-Edelstein effect (IREE) is made possible with the integr…
Structural analysis of polycrystalline graphene systems by Raman spectroscopy
J. Ribeiro-Soares, M. E. Oliveros, C. Garin +12
A theoretical model supported by experimental results explains the dependence of the Raman scattering signal on the evolution of structural parameters along the amorphization traje…
Magnetic reconfiguration of MnAs/GaAs(001) observed by Magnetic Force Microscopy and Resonant Soft X-ray Scattering
L. N. Coelho, R. Magalhães-Paniago, B. R. A. Neves +7
We investigated the thermal evolution of the magnetic properties of MnAs epitaxial films grown on GaAs(001) during the coexistence of hexagonal/orthorhombic phases using polarized…
Domain wall formation and spin reorientation in finite-size magnetic systems
Rafael M. Fernandes, Harry Westfahl, Rogério Magalhães-Paniago +1
We investigate the formation of stable one-dimensional Néel walls in a ferromagnetic slab with finite thickness and finite width. Taking into account the dipolar, the exchange and…
Atomic ordering in self-assembled Ge:Si(001) islands observed by X-ray scattering
A. Malachias, T. U. Schulli, G. Medeiros-Ribeiro +4
X-ray diffuse scattering in the vicinity of a basis-forbidden (200) Bragg reflection was measured for a sample with uncapped self-assembled Ge islands epitaxially grown on Si(001).…
