Compositional and magnetic properties of iron nitride thin films
(1990) [Journal article]The compositional and magnetic properties of iron-nitride thin films deposited by de reactive magnetron sputtering under various nitrogen partial pressure conditions have been investigated by x-ray diffraction, Mossbauer ... -
Corrosion behavior of steel coated with thin film tin/ti composites
(1993) [Journal article]Thin film multilayered TiN/Ti composites are investigated as a possible alternative for protective coating of steels. Corrosion tests based in cyclovoltametry made in a buffered acetic acid solution reveal that multilayered ... -

Epitaxial fe/cu superlattices on Si(111)
(1992) [Journal article]We report on the successful epitaxial growth of Fe/Cu superlattices on Si( 111) wafers at room temperature. The superlattices were characterized with x-ray diffraction, conversion electron Mossbauer spectrometry, and ... -
Estudo do comportamento magnético e magnetoresistivo em multicamadas de filmes finos
(1994) [Thesis]Este trabalho envolve o estudo de multicamadas de filmes finos magnéticos e está dividido em duas partes: estudo do comportamento magnético e formação de fases em sistemas de multicamadas de Fe/Nd(B) e o estudo da ... -
Ferromagnetic resonance in ag coupled ni films
(1993) [Journal article]We present an X-band ferromagnetic resonance (FMR) study of polycrystalline single Ni films and of two Ni layers separated by an Ag layer at room temperature. Films were deposited by sputtering on glass using Ag over- and ... -
Ferromagnetic resonance of fe(111)/cu(111)multilayers
(1994) [Journal article]Ferromagnetic resonance at 9.4 GHz has been used to characterize several samples of Fe sing1e-crystal films and Fe/Cu multilayers prepared by electron-beam deposition on HF-etched, hydrogen-terminated Si(111). Resonance ... -
Filmes finos de óxido de estanho: efeitos da implantação iônica e de ambientes oxidantes e redutores
(1990) [Dissertation]Filmes finos de óxido de estanho depositados por "sputtering" reativo foram caracterizados com bases em análises feitas por Espalhamento Nuclear Ressonante, Espectroscopia por Retroespalhamento Rutheford, Espectroscopia ... -
Instrução programada em física via televisão
(1973) [Dissertation]O mesmo programa, elaborado pelo autor, foi apresentado em dois semestres consecutivos a amostras randômicas de alunos universitários matriculados em um curso de Física geral, sob duas formas diferentes. A esperiência ... -
Magnetic susceptibility of fe/cu multilayers : ferromagnetic, antiferromagnetic, and spin-glass phases
(1998) [Journal article]In this work we present low-field magnetic measurements on multilayers of Fe 1.5 nm and Cu 1.5 nm layers, repeated 10 times, grown on Si~111! and Fe 5 nm/CaF2 40 nm/Si(111), substrates. Magnetic characteristics of a ... -
Mistura atômica na bicamada Fe/Al induzida por feixe de íons
(1991) [Thesis]Quando dirigimos nossa atenção ao deslocamento e rearranjo dos átomos de um alvo submetido à irradiação com feixe de Íons energéticos, designamos o fenômeno como Mistura Por Feixe De Íons, ou abreviadamente, IM ( do inglês ... -
Mossbauer effect study of cu/sub 2/mnal/sub 1-x/sn/sub x/ compounds
(1980) [Journal article]Results of a Mõssbauer effect study of a range of Cu2MnA1t-xSnx compounds are presented for x=0.05, 0.10, 0.15, 0.25, 0.50, and 0.75. The hyperfine magnetic field at Sn nuclei is proportional to a number of Sn atoms ... -
Sistemáticas na resistividade elétrica de ligas de Heusler
(1982) [Thesis]Discute-se os resultados experimentais de resistividade elétrica de ligas de Heusler, B2 e C1b. Obtém-se sistemáticas comuns ás várias ligas em temperaturas altas e intermediárias e faz-se a sua interpretação. Evidencia-se ... -
Structural change and heteroepitaxy induced by rapid thermal annealing of CaF/sub 2/ films on Si(111)
(1998) [Journal article]In this article we show that heteroepitaxial CaF2 films can be induced on Si~111! with a rapid thermal anneal. The change from preferentially oriented polycrystals to a single crystal with type- B epitaxy is visible by ... -
Study on direct current reactive sputtering deposition of aluminum nitride thin films
(1992) [Journal article]Aluminum nitride thin films were deposited by dc magnetron reactive sputtering. The deposition parameters (cathode voltage, incident power, total pressure, and N2 partial pressure) were correlated and their influences on ... -
Study on radio frequency reactive sputtering deposition of silicon nitride thin films
(1992) [Journal article]A rf magnetron sputtering apparatus operating at constant gas pressure was used to deposit silicon nitride thin films in an Ar-N2 plasma. The nitrogen partial pressure, incident rf power, and the deposition time were varied ...
