“…A low energy tail of the Co peak was also seen developing in the annealed samples, which is an indication of the formation of Co-silicide due to diffusion of Co into the Si substrate. El Asri et al [14] demonstrated that Co diffusion into Si is initiated above 200 1C to form Co-silicide. Absolute RBS counts of the two peaks also dropped in the annealed samples possibly due to the formation of Co-silicide [15].…”

“…The slightly reduced color scale in the images of the bottom row of Figure 7 with respect to those of the top row account for a slightly lower anisotropy value of the Co grains, which is in agreement with the slightly lower coercivity reported in Figure 6. Moreover, a 2D power spectral density [55] calculated on the MFM images of Figure 7 reports a slight decrease of the magnetic features size after annealing, as evidenced in Figure 8 for two examples, as-prepared sample and annealed at 6 T. The appearance of a maximum in the blue curve at higher frequencies (shorter wavelengths) marks the decrease of magnetic features size that can be attributed to a slight increase of the magnetic anisotropy with annealing; a similar behavior has been observed in L 10 Fe-Pt films [55]. This is in agreement with the measured hysteresis loops, as discussed in Figures 5 and 6.…”

Superimposed external magnetic fields during electrodeposition process offers the possibility to tailor microstructure and properties of the obtained films in a very efficient, contactless, and easily controllable way, what is caused by so-called magnetohydrodynamic MHD effect. On the other hand, the nonequilibrium state of aselectrodeposited nanocrystalline films provides a strong thermodynamic potential for microstructural transformation. This means that the benefit effect of magneto-electrodeposition on a nanocrystalline film can be completely consumed by a thermal exposure at relatively low temperature. Magnetic field annealing has been confirmed to be useful for tailoring the microstructure of as-deposited nanocrystalline films for their widespread uses.The particular interest of this book Chapter Growth of Co-based magnetic thin films by magnetic fields MF assisted electrodeposition and heat treatment is the finding that the microstructure and magnetic properties of nanocrystalline Co-based alloys and oxides like CoX X= Cu, Ni, NiP, FeO are improved by imposition of MF during elaboration process or post-annealing process. "ccording to the previous study, the targeted scientific activities pay more attention to develop alloys and oxides in nanoscale using pulsed electrodeposition assisted by high magnetic field HMF . Note Since the instantaneous current density during pulse electrodeposition is higher than that during direct current plating, the microstructure of the nano-scale electrodeposits can be more easily controlled by perturbing the desorption/adsorption processes occurring in the pulse electrodeposition process .During the experiment, high magnetic field is an in-situ method for the control of electrodeposition process. The obtained material is then annealed or oxidized after

“…[2,3] It established that the optical emission of secondary excited particles provides important information on both the formation mechanism of these particles and the possibility of their uses in various applications. [2][3][4][5] These studies show that photon emission is found to be sensitive depending on the surface conditions. An enhancement of photon intensity has been observed when a reactive gas like oxygen covered a surface under ion bombardment.…”

Clean and oxygen-covered nickel and nickel oxide were bombarded by 5 keV krypton I ions under a relatively high vacuum. Optical spectra resulting from ion bombardment of the nickel target consist of series of sharp lines attributed to the neutral nickel. These lines were observed in the spectra of clean nickel and nickel oxide at the same wavelengths but with different intensities. The difference in the observed photon yield is discussed in terms of the electron transfer processes between the excited sputtered and electronic levels of the surface.
