Magnetoimpedância em multicamadas de Ni81Fe19/Cu com a corrente de sonda perpendicular ao plano do filme
(Universidade Federal de Santa Maria, 2006-06-02)
In this work the behavior of the magnetoimpedance (MI) in ferromagnetic
multilayered (Ni81Fe19/Cu) produced by magnetron sputtering was studied. In all
measurements, the probe current was applied perpendicularly to the ...
Avaliação do "magnetron sputtering" como técnica para obtenção de MgB2
(Universidade Federal de Santa Maria, 2014-08-26)
In this work a survey of the potentialities and limitations of magnetron sputtering as a
tool for the production of MgB2 superconductors thin films has been made. Instead of the usual
approaches, like co-deposition onto ...
Estudo de impureza de európio em PbSe e PbTe. Uma investigação de primeiros princípios
(Universidade Federal de Santa Maria, 2014-01-30)
In this work properties were studied the structural, electronic and magnetic semiconductors
PbSe and PbTe doped with europium (Eu) in the crystalline phase. The
investigation is performed within the density functional ...
Análise de populações estelares e subestruturas em aglomerados de galáxias
(Universidade Federal de Santa Maria, 2015-08-25)
In this work, we investigated differences between stellar populations of galaxies that are part
of a cluster with and without substructures. We used optical spectra obtained from Sloan Digital
Sky Servey III DR10 for the ...
Cinemática e distribuição do gás ionizado na região central das galáxias Seyfert NGC4501 e NGC3982
(Universidade Federal de Santa Maria, 2015-02-25)
We present two-dimensional (2D) maps for emission-line fluxes and ratios and kinematics for
the central regions of the Seyfert galaxies NGC 4501 and NGC 3982, from optical spectra obtained
with the GMOS (Gemini Multi ...
Caracterização de filmes finos magnéticos em altas frequências
(Universidade Federal de Santa Maria, 2014-08-29)
In order to determine the complex permeability of ferromagnetic samples in the GHz
range, measurement techniques with transmission lines are most appropriate. These techniques
use the modification of the scattering ...
Modelo simplificado para turbulência na camada limite noturna
(Universidade Federal de Santa Maria, 2016-03-08)
The appropriate estimation of turbulent fluxes in very stable conditions is a great challenge
for numerical models that simulate the average behavior of the stable boundary layer.
Although many features of the flow are ...
Calor específico de um modelo teórico para o composto URu2Si2
(Universidade Federal de Santa Maria, 2016-01-29)
The Heavy fermion URu2Si2 compound have attracted much interest in the last
decades due to its unusual behaviors and still an unsolved problem in Condensed Matter
Physics. Specific heat measurements in URu2Si2 compounds ...
Estudo de primeiros princípios de nanofios de inas submetidos a tensões extremas
(Universidade Federal de Santa Maria, 2015-03-30)
The ability to manipulate materials at the atomic scale turn it possible to look
for materials at the nanoscale that can supersede the performance of their bulk counterparts
in specific tasks. Nanowires, due to their ...
Conjunto de testes de garantia de qualidade de um software para planejamento radioterápico
(Universidade Federal de Santa Maria, 2014-05-29)
Radiotherapy can be highlighted as one possible treatment of cancer. From this point of view, the planning system for radiotherapic treatment is crucial. In order to check the software for the computerized planning of the ...
