The objective of this paper is to present the assumptions and conditions of the implementation of development programs for suppliers. For many companies, especially for multinationals forming partnerships with suppliers is a very important element of mutual building a competitive advantage based on the principle of win-win. The implementation of these programs have been initiated by car manufacturers in order to improve the quality of technical and organizational capabilities of suppliers and lowering costs. Currently, more and more international OEM conducting the global expansion developed such programs to support local suppliers, evolving their capabilities through transfer of knowledge.

Sputtered NiFe/Au/Co/Au layers with noncollinear magnetizations are of scientific interest for unusual magnetization behavior and their potential application in spintronics. In this paper, we propose to use a material selective sensitivity of magneto-optical Kerr effect for separation of signals from different materials in a bilayer system. The materials selective sensitivity is demonstrated on a sample with two mutually perpendicular Co and NiFe wedges.

We report on hard and soft X-ray reflectivity investigations of (Ni_{80}Fe_{20} (2.2 nm)/Au(2.3 nm)/Co(0.8 nm)/Au(2.3 nm))_{10} multilayers. Specular reflectivity curves were measured with Cu K_{α} radiation and circularly polarized synchrotron radiation tuned to Co L_{3} and Ni L_{3} absorption edges. Structural properties of the multilayers were determined from the hard X-ray reflectivity curve. Comparison of reflectivity curves taken at different photon energies shows: (i) small difference in peak positions in dependence of reflectivity versus scattering vector q, (ii) different shapes of satellite Bragg peaks, (iii) different ranges of q for appearance of the Kiessig fringes. Analysis of soft X-ray reflectivity curves taken as a function of magnetic field allows to determine magnetic properties of Co and NiFe layer specifically.

The influence of He^+ ion bombardment on magnetoresistance, magnetization reversal and domain structure of sputtered (Ni_{80}Fe_{20}(2 nm)/Au(2 nm)/Co(0.6 nm)/Au(2 nm))_{10} multilayers was investigated. The samples were bombarded using He^+(30 keV) ions with fluences D varied from 10^{13} to 3×10^{16} He^+/cm^{2}. With increasing D the following changes in magnetic properties were observed: (i) exponential decay of the saturation field of Co layers, (ii) progressive decrease in magnetoresistance as a result of degradation of Co layers perpendicular anisotropy, (iii) linear decrease in stripe domain period with log(D).

Sputter deposited (Ni_{80}Fe_{20}/Au/Co/Au)_{10} multilayers, characterized by alternating in-plane and perpendicular anisotropies of the NiFe and Co layers, respectively, and out-of-plane stripe (labyrinth) domain structure in the Co layers, were bombarded by He^+-ions (10 keV) through a mask consisting of polystyrene nanospheres with a diameter of 470 nm. The changes of multilayers magnetic properties after ion bombardment are correlated with the used mask structure.
