“…The choice of the method of synthesis of barium hexaferrite depends on the structure and properties of the intended final product. Therefore, to obtain monocrystalline barium hexaferrite, the method of spontaneous crystallization in an air atmosphere using a resistance furnace is used [10]. In addition, other synthesis methods of barium hexaferrite are often used, such as sol-gel [11][12][13], co-precipitation [14], solid-state synthesis [15] and the method of hydrothermal reactions [16].…”

The article shows the results of a research in which barium hexaferrite samples of the BaFe11M1O19 (M= Al, Ti and Mn) composition were obtained by solid-state synthesis. Samples substituted with titanium, aluminum, and manganese were obtained in a tubular furnace at an exposure time of 5 hours at a temperature of 1350°C, the sample, substituted with manganese, it was obtained at a temperature of 1250°C. The chemical composition was controlled using electron microscopy the samples obtained correspond to the initial composition with sufficient accuracy. Hexagonal plates represent the structure of all the obtained samples. According to X-ray phase analysis, all samples are monophasic and have the structure of barium hexaferrite. Using the data of powder X-rays, the parameters of the unit cell of the studied samples were calculated, when iron atoms are substituted by titanium or aluminum or manganese atoms, the crystal lattice is distorted, while its change is not the same for different crystallographic directions. During the doping of barium hexaferrite with titanium, aluminum or manganese atoms, the Curie temperature decreases. This is due to a decrease in the exchange interaction forces during the modification of the barium hexaferrite matrix. The aim of this study was to study the structure and change of the lattice parameters, the Curie temperature, depending on the substitution element.

Knowledge Intensive Business Services (KIBS) are widely argued to be important actors in innovation systems. They are active both innovating themselves, and by providing their clients with important knowledge and learning opportunities. This study uses survey data to investigate the mechanisms of knowledge transfer and innovativeness improvement through the provision of KIBS. The empirical core of the paper is a set of Russian surveys of KIBS and their clients: KIBS are a fairly new phenomenon in Russia, so this provides an opportunity to contrast KIBS supplier-client relationships featuring more and less experienced customers. Many of the KIBS firms' services are highly tailored to customer specificities, and we consider how far this is minor customisation and how far novel products (and thus potentially product innovations) are involved. These services typically involve KIBS consumers into a coproduction process, where both the formal supplier and the formal user of the service are engaged together in service production. Knowledge transfers through learning-by-doing in such cases affect customers' propensity to innovate and improve their absorptive capacity. The paper concludes that the generation of innovations through KIBS may well be a self-sustaining process. In this process, service providers are incentivised to engage in service innovations by more innovative customers' demand for highly individualised services. In turn, the process stimulates the innovativeness of customers, as they engage in learning-by-doing through coproduction.JEL Classification: D83, L84, O32.
