Abstract

The crystal structure and composition of the Co–Ni–Fe films has been analyzed, and the effect of the deposition rate on the coefficient dB/dH of conversion of a weak magnetic field into the magnetic induction has been established. The presence of oxygen on the film surface indicates the porosity of the Co–Ni–Fe film structure, which is confirmed by the surface roughness. Electrochemical deposition from a chloride electrolyte has demonstrated the possibility of controlling the magnetic properties of the films by improving the deposition technique. The chloride electrolyte with filtration and boric acid, saccharin, and hydrochloric acid additives in a concentration ratio of C_Co : C_Ni : C_Fe = 1 : 1 : 1 ensures, at a temperature of 70°C, the reproducible electrochemical deposition of the Co–Ni–Fe films with low stresses, a uniform structure, and a high coefficient of conversion of a weak magnetic field into the magnetic induction.

电化学沉积法获得的 Co-Ni-Fe 薄膜结构对其磁性能的影响

分析了 Co-Ni-Fe 薄膜的晶体结构和组成，并确定了沉积速率对弱磁场转化为磁感应强度的系数 dB/dH 的影响。薄膜表面氧的存在表明 Co-Ni-Fe 薄膜结构具有多孔性，表面粗糙度也证实了这一点。氯化物电解液的电化学沉积证明了通过改进沉积技术来控制薄膜磁性能的可能性。氯化物电解液经过过滤，添加了硼酸、糖精和盐酸，浓度比为 CCo ：CNi ：CFe = 1 : 1 : 1 的氯化物电解质，可确保在 70°C 的温度下，钴-镍-铁薄膜的电化学沉积具有可重复性、应力小、结构均匀以及将弱磁场转化为磁感应强度的系数高等特点。

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
