Desenvolvimento de um modelo lagrangiano para estimar a dispersão de escalares passivos em condições de meandro do vento horizontal
(Universidade Federal de Santa Maria, 2017-02-24)
The description of the effects of the wind meandering in the scalar dispersion is a challenging
task, since this type of flow represents a physical state characterized by multiple
scales. In this study, a Lagrangian ...
Formação de texturas cristalográficas em filmes finos de NbN
(Universidade Federal de Santa Maria, 2017-12-20)
Niobium nitride (NbN) thin films can be hard and resistant not only to mechanical wear but
also to chemically aggressive atmospheres. Additionally, they can present a superconducting
transition in temperatures that are ...
Distribuição e manipulação de coerência quântica em sistemas multipartidos
(Universidade Federal de Santa Maria, 2017-02-24)
Repeatedly in the field of Quantum Information Science (QIS) it’s essentially required of
physical systems the quantification concerning its quantum phenomena, such as Quantum
Coherence (QC) relying in quantum superposition ...
Efeito hall de spin inverso em multicamadas de Ta/NiFe/FeMn/Ta
(Universidade Federal de Santa Maria, 2017-10-27)
In the present thesis, the generation of a dc voltage in exchange-biased Ta/NiFe/FeMn/Ta
multilayers at ferromagnetic resonance was investigated. This dc signal is related to two distinct
phenomena, namely, the spin ...
Magnetorresistência e correntes de spin em Multicamadas de Ni81Fe19/ZnO/Pd
(Universidade Federal de Santa Maria, 2017-03-02)
In this work, we analyzed samples of thin films Ni81Fe19 and Pd with ZnO spacer. Ni81Fe19
is a ferromagnet with a low saturation magnetic field. Pd is a normal metal with high spinorbit
coupling, much used in spin Hall ...
