H. Demydenko, S. I. Protsenko, D. M. Kostyuk, I. V. Cheshko // Journal of Nano- and Electronic Physics. — 2011. — Vol.3, №4. — Р. 81-87.0000-0002-8070-1610http://essuir.sumdu.edu.ua/handle/123456789/36002The construction of module for the automated measurement of the magnetoresistance (MR) and coercive force (Вс) in spin-valve structures based on Co and Cu or Au film systems was proposed. The peculiarities of dependences of MR and Bc from angle between substrate plane and direction of the external magnetic field induction were studied. The abrupt changes of MR and Вс in the range of 70 -90 were observed. The dependence character of MR from is defined by the degree of solubility of atoms of the bottom ferromagnetic layer Co(3 nm) or Co(20 nm) in layer Cu(6 nm), since Co(3 nm) atoms are dissolved almost completely, but Co(20 nm) ones – only partially. In this case, remagnetization of magnetic layers of Co(20 nm) and solid solution (s.s.) [Cu, Co(3 nm)] as well as Со(3 nm) and [Co(20 nm-x)] + s.s.[Cu, Co(x)] is realized in different ways. This fact causes an increase or decrease of MR.
