CDW signatures in the electronic structure of LaSb2 at 13 K and metal-insulator transition

Autor: Palacio, I., Obando-Guevara, J., Chen, L., Nair, M. N., Barrio, M. A. González, Papalazarou, E., Fèvre, P. Le, Luccas, R. F., Suderow, H., Canfield, P., Taleb-Ibrahimi, A., Michel, E. G., Mascaraque, A., Tejeda, A.

Light rare-earth antimonide LaSb2 is a material susceptible to nesting and exhibits a Charge Density Wave (CDW) at 355 K as well as superconductivity below 1.2 K. In the seek for additional CDW transitions, we have studied the temperature-dependent o

Proximity driven commensurate pinning in YBa2Cu3O7 through all-oxide magnetic nanostructures

Autor: Rocci, M., Azpeitia, J., Perez-Muñoz, J. Trastoy A., Cabero, M., Luccas, R. F., Munuera, C., Mompean, F. J., Garcia-Hernandez, M., Bouzehouane, K., Sefrioui, Z., Leon, C., Rivera-Calzada, A., Villegas, J. E., Santamaria, J.

The design of artificial vortex pinning landscapes is a major goal towards large scale applications of cuprate superconductors. While disordered nanometric inclusions have shown to modify their vortex phase diagram and to produce enhancements of the

Magnetic field dependence of the density of states in the multiband superconductor $\beta$-Bi$_2$Pd

Autor: Herrera, E., Guillamon, I., Galvis, J. A., Correa, A., Fente, A., Luccas, R. F., Mompean, F. J., Garcia-Hernandez, M., Vieira, S., Brison, J. P., Suderow, H.

Publikováno v: Phys. Rev. B 92, 054507 (2015)

We present very low temperature scanning tunneling microscopy (STM) experiments on single crystalline samples of the superconductor $\beta$-Bi$_2$Pd. We find a single fully isotropic superconducting gap. However, the magnetic field dependence of the

Superconductivity and magnetism on flux grown single crystals of NiBi3

Autor: Silva, B., Luccas, R. F., Nemes, N. M., Hanko, J., Kulkarni, M. R. Osorio P., Mompean, F., Garcia-Hernandez, M., Ramos, M. A., Vieira, S., Suderow, H.

We present resistivity, magnetization and specific heat measurements on flux grown single crystals of NiBi3. We find typical behavior of a type-II superconductor, with, however, a sizable magnetic signal in the superconducting phase. There is a hyste

IFRS accounting systems classification: A new emerging cluster

Autor: Sarquis, R., Luccas, R., Lourenço, I., Dalmácio, F.

This study aims to identify the position of emerging countries in the IFRS accounting systems’ classification proposed by Nobes (2011). In spite of the international accounting harmonization efforts around the convergence to IFRS, there is empirica

Classificação dos sistemas contábeis na era IFRS: uma análise dos países da América Latina

Autor: Sarquis, R., Luccas, R., Lourenço, I.

Este estudo tem como objetivo propor uma classificação, baseada nos sistemas contábeis, de cinco países da América Latina que já adotaram as normas internacionais de contabilidade (IFRS). Mais especificamente, busca caracterizar o sistema cont�
