Realization of Rectangular Artificial Spin Ice and Direct Observation of High Energy Topology
I. R. B. Ribeiro, F. S. Nascimento, S. O. Ferreira +7
In this letter, we have constructed and experimentally investigated frustrated arrays of dipoles forming two-dimensional artificial spin ices with different lattice parameters (rec…
Ferromagnetic resonance and magnetoresistive measurements evidencing magnetic vortex crystal in nickel thin film with patterned antidot array
I. R. B. Ribeiro, J. F. Felix, L. C. Figueiredo +6
Ferromagnetic vortices deliver robust out-of-plane magnetization at extremely small scales. Their handling and creation therefore has high potential to become a necessary ingredien…
Temperature effect on (2+1) experimental Kardar-Parisi-Zhang growth
R. A. L. Almeida, S. O. Ferreira, I. R. B. Ribeiro +1
We report on the effect of substrate temperature (T) on both local structure and long-wavelength fluctuations of polycrystalline CdTe thin films deposited on Si(001). A strong T-de…
Vortex-crystal pattern in an anti-artificial spin ice system
C. I. L. de Araujo, R. C. Silva, I. R. B. Ribeiro +6
We have proposed in this work an original system composed by anti-dots nanopatterned in a ferromagnetic thin film, mimicking negatively the structure of an articial spin ice. In th…
Modelling of epitaxial film growth with a Ehrlich-Schwoebel barrier dependent on the step height
F. F. Leal, S. C. Ferreira, S. O. Ferreira
The formation of mounded surfaces in epitaxial growth is attributed to the presence of barriers against interlayer diffusion in the terrace edges, known as Ehrlich-Schwoebel (ES) b…
Faceted anomalous scaling in the epitaxial growth of semiconductor films
Fábio S. Nascimento, Silvio C. Ferreira, Sukarno O. Ferreira
We apply the generic dynamical scaling theory (GDST) to the surfaces of CdTe polycrystalline films grown in glass substrates. The analysed data were obtained with a stylus profiler…
