FMR study of ultrahigh vacuum e-beam evaporated Co 23Cu 77 nanogranular films: Magnetotransport properties
(2006)
The magnetic, magnetotransport and structural properties of Co 23Cu 77 granular thin films (7-43 nm) have been investigated using ferromagnetic resonance (FMR) and high-resolution XRD techniques. Co particles possess a ...
Excited state dynamics of nanocrystalline VO2 with white light continuum time resolved spectroscopy
(Elsevier Science BV, 2014)
In an attempt to use ultrafast pump probe spectroscopy technique with white light continuum to reveal wavelength dependent dynamics of VO2, bandgap needs to be opened. Therefore, nanostructured amorphous and crystalline ...
Determination of thickness, density and roughness of Co-Ni-Al single and multiple layer films deposited by high-vacuum e-beam evaporation on different substrates
(2006)
Thickness, density, surface and interface roughness of Al-Co-Ni single and multiple layer films deposited by high-vacuum e-beam evaporation on different substrates were investigated using X-ray reflectivity (XRR). The ...
Effect of bias voltage on tunneling mechanism in Co40Fe40B20/MgO/Co40Fe40B20 pseudo-spin valve
(Elsevier Science BV, 2015)
Bias voltage dependence of tunneling mechanism has been systematically investigated in Co40Fe40B20 (2.1 nm)/MgO (2 nm)/Co40Fe40B20 (1.7 nm) pseudo-spin valve magnetic tunnel junction deposited using the combination of the ...
The third order nonlinear optical characteristics of amorphous vanadium oxide thin film
(Springer, 2011)
We studied the nonlinear absorptive characteristics (saturation intensity threshold and effective nonlinear absorption coefficients) and nonlinear refraction in a 50-nm-thick VO (x) thin amorphous film prepared by pulsed ...
Deposition potential dependence of composition, microstructure, and surface morphology of electrodeposited Ni-Cu alloy films
(Springer New York LLC, 2012)
Composition, microstructure, and surface morphology of Ni-Cu alloy films electrodeposited at different deposition potentials have been investigated. The microstructural analysis carried out by using X-ray diffraction (XRD) ...
Effect of Thickness on the Structural, Microstructural, Electrical and Magnetic Properties of Ni Films Elaborated By Pulsed Electrodeposition on Si Substrate
(World Scientific Publ Co Pte LTD, 2018)
We have studied the effect of thickness on the structural, microstructural, electrical and magnetic properties of Ni films electrodeposited onto n-Si (100) substrates. A series of Ni films have been prepared for different ...
High-surface-area SBA-15-SO3H with enhanced catalytic activity by the addition of poly(ethylene glycol)
(Springer, 2013)
The influence of poly(ethylene glycol) (PEG) and synthesis temperature in the synthesis of SBA-15-SO3H was investigated to evaluate the catalytic activity in the esterification of propionic acid with methanol. The catalysts ...
Effect of calcination temperature on the structural and magnetic properties of Ni/SBA-15 nanocomposite
(Springer, 2015)
The effect of calcination temperature on the structural and magnetic properties of Ni/SBA-15 nanocomposite prepared by reductant-impregnation method was studied using SBA-15 mesoporous silica as support. The structure, ...
Synthesis, characterization and catalytic behavior of functionalized mesoporous SBA-15 with various organo-silanes
(Academic Press Inc Elsevier Science, 2012)
Mesoporous silica SBA-15 has been synthesized and functionalized by one-step synthesis method to widen their various application possibilities. In this study, phenyltrimethoxysilane (PTMS), 3-mercapto-propyltrimethoxysilane ...
