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.
