“…15 Demanding to avoid loss of compositional control, researchers use one multielemental material source when applying, for example, pulsed laser deposition or magnetron sputter deposition. [16][17][18][19] In the latter case, it is well known that this approach does not guarantee compositional control due to the transport of the sputter particles through the sputter gas 20 and the preferential sputtering by energetic particles during thin film growth. Nevertheless, this technique is widely used in an industrial environment.…”

The influence of the composition on the crystallographic properties of deposited Mg(M)O (with M=Al, Cr, Ti, Y, and Zr) films is studied. For a flexible control of the composition, dual reactive magnetron sputtering was used as deposition technique. Two different approaches to predict the composition are discussed. The first is an experimental way based on the simple relationship between the deposition rate and the target-substrate distance. The second is a route using a Monte Carlo based particle trajectory code. Both methods require a minimal experimental input and enable the user to quickly predict the composition of complex thin films. Good control and flexibility allow us to study the compositional effects on the growth of Mg(M)O films. Pure MgO thin films were grown with a (111) preferential out-of-plane orientation. When adding M to MgO, two trends were noticed. The first trend is a change in the MgO lattice parameters compared to pure MgO. The second tendency is a decrease in the crystallinity of the MgO phase. The experimentally determined crystallographic properties are shown to be in correspondence with the predicted properties from molecular dynamics simulations

“…In addition, MI depends on the changes in the field sensitivity of permeability and the skin effect. Magnetic properties of ferromagnetic specimen in the forms of ribbons [6] and thin films [7] are sensitively influenced by structural defects. The structural defects as regions of lower or higher density are the sources of compressive or tensile internal stresses and they influence the domain structure and indirectly the magnetization process [8,9].…”

Magnetoimpedance (MI) and field sensitivity of CoFeSiB amorphous ribbons were investigated at frequencies ranging from 0.2 to 12 MHz after tensile stress applied. Experimental results indicate that the MI of amorphous ribbons can be significantly improved by applying a suitable longitudinal tensile stress. Applying tensile stress induces a rearrangement of domain walls which influences the circumferential anisotropy and magnetic permeability result in improving the MI response. The maximum MI response of 145 % and maximum field sensitivity of 6.32 %/Oe at frequency of 4 MHz were obtained, when tension was equivalent to 120 MPa. So the tensile stress as new method can be effective, cheap, and fast in sensor applications, and result of this investigation can be applied for the design of the stress sensors based on the giant magnetoimpedance effect.

“…[1][2][3][4]. It has been well known that previous amorphous alloy films form mostly via sputtering or depositing of metal elements on substrates instead of the glass transition [1][2][3][4][5][6][7]. These amorphous films have manufacturing defects such as interfaces and cavities that generally lead to mechanical failure in service.…”
