Abstract

The effect of the subphase temperature on the formation of nickel arachinate clusters under a monolayer of arachidic acid was studied. The subphase temperature varied in the range from 10° to 30°C with a step of 4°C. The influence of temperature on the compressibility of the monolayer and the area occupied by one molecule in the Langmuir monolayer of nickel araquinate is demonstrated. The effect of temperature on the morphology of Langmuir-Blodgett films formed on their basis was also studied. It was found that, as the temperature changes, the number of nickel clusters increases and their sizes decrease. This is due to a change in the rate of growth and dissolution of clusters with a change in temperature. The distribution of clusters in the resulting film was random, however, they can be structured using external magnetic fields. Using the magnetic properties of NiArch clusters will make it possible to purposefully change the film structure by an external magnetic field. The results obtained are of great importance for practical applications in the creation of multilayer composite coatings with controlled magnetic properties. These films can be further used as touch coatings for acoustic and electronic sensors.

温度对花生酸镍和花生酸镍簇形成Langmuir单层膜的影响

研究了亚相温度对花生酸单层下花生酸镍簇形成的影响。亚相温度在10 ~ 30℃范围内变化，步长为4℃。研究了温度对araquinate镍的Langmuir单层可压缩性和单个分子所占面积的影响。研究了温度对在此基础上形成的Langmuir-Blodgett薄膜形貌的影响。结果表明，随着温度的变化，镍团簇数量增加，尺寸减小。这是由于团簇的生长和溶解速度随温度的变化而变化。所得到的薄膜中的团簇分布是随机的，然而，它们可以利用外部磁场进行结构化。利用NiArch团簇的磁性可以通过外部磁场有目的地改变薄膜结构。所得结果对制备磁性能可控的多层复合镀层具有重要的实际应用价值。这些薄膜可以进一步用作声学和电子传感器的触摸涂层。

期刊介绍： Journal “Radioelectronics. Nanosystems. Information Technologies” (abbr RENSIT) publishes original articles, reviews and brief reports, not previously published, on topical problems in radioelectronics (including biomedical) and fundamentals of information, nano- and biotechnologies and adjacent areas of physics and mathematics. The authors of the journal are academicians, corresponding members and foreign members of the Russian Academy of Natural Sciences (RANS) and their colleagues, as well as other russian and foreign authors on the proposal of the members of RANS, which can be obtained by the author before sending articles to the editor or after its arrival on the recommendation of a member of the editorial board or another member of the RANS, who gave the opinion on the article at the request of the editior. The editors will accept articles in both Russian and English languages. Articles are internally peer reviewed (double-blind peer review) by members of the Editorial Board. Some articles undergo external review, if necessary. Designed for researchers, graduate students, physics students of senior courses and teachers. It turns out 2 times a year (that includes 2 rooms)
