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 ...
Formação sequencial de ligações carbono-carbono/carbono-selênio mediada por cloreto férrico e dicalcogenetos de diorganoíla: síntese e reatividade de 2-organocalcogenil-naftalenos
(Universidade Federal de Santa Maria, 2017-07-31)
In the present study, a series of aryl alkynols functionalized was subjected to intramolecular cyclization reaction promoted by iron(III) chloride and diorganyl dichalcogenides allowing the synthesis of 2-organoselenyl-n ...
