Item Electrophysical Properties of Granular Film Alloys Based on Fe and Ag or Au(Sumy State University, 2015) Шабельник, Юрій Михайлович; Шабельник, Юрий Михайлович; Shabelnyk, Yurii Mykhailovych; Чешко, Ірина Володимирівна; Чешко, Ирина Владимировна; Cheshko, Iryna Volodymyrivna; Пазуха, Ірина Михайлівна; Пазуха, Ирина Михайловна; Pazukha, Iryna Mykhailivna; Проценко, Іван Юхимович; Проценко, Иван Ефимович; Protsenko, Ivan YukhymovychThe experimental results of electrophysical properties of granular film alloys based on Fe and Ag or Au are presented. It is established that the value of the temperature coefficient of resistance depends on the total thickness of the samples and the concentration of magnetic component. The components concentration in the system is shown to affect the formation of the solid solution and the granular film alloy. The optimal concentration value of Fe, in which the thermally stable solid solution forms, is 45 at. %.Item Тemperature and Concentration Dependences of Anisotropic Magnetoresistance Film Materials(Sumy State University, 2015) Проценко, Сергій Іванович; Проценко, Сергей Иванович; Protsenko, Serhii Ivanovych; Гричановська, Оксана Анатоліївна; Гричановская, Оксана Анатольевна; Hrychanovska, Oksana Anatoliivna; Однодворець, Лариса Валентинівна; Однодворец, Лариса Валентиновна; Odnodvorets, Larysa Valentynivna; Проценко, Іван Юхимович; Проценко, Иван Ефимович; Protsenko, Ivan Yukhymovych; Shumakova, M.O.In framework the phenomenological approach the question of the temperature dependence of anisotropic magnetoresistance (AMR) at the fixed value inducing an external magnetic field (B) and the concentration dependence of AMR at the fixed B and T were analyzes. The obtained ratio to assess and predict the magnitude of thermal and concentration coefficients of AMR, virtually can not be done in the classical model, since it allows complex ratio with many uncertain parameters.Item Phenomenological Theory of Strain Effect in Granular Film Alloys(Sumy State University, 2014) Однодворець, Лариса Валентинівна; Однодворец, Лариса Валентиновна; Odnodvorets, Larysa Valentynivna; Shumakova, M.O.; Проценко, Іван Юхимович; Проценко, Иван Ефимович; Protsenko, Ivan Yukhymovych; Шабельник, Юрій Михайлович; Шабельник, Юрий Михайлович; Shabelnyk, Yurii Mykhailovych; Шумакова, Наталія Іванівна; Шумакова, Наталия Ивановна; Shumakova, Nataliia IvanivnaThe elementary theory tensoresistive effect in granular thin film materials was proposed. Analyzed limiting cases of large, small and normal concentration of magnetic granules. It is concluded that in all three cases, the strain coefficient is defined tensoresistive properties of the matrix solid solution film samples as granules sold ballistic electrocarry charge.
