The structure and magnetic properties of different titanium oxide films doped with
magnetic impurities are investigated both in the as-deposited state and after thermal
treatments in a vacuum. The samples were characterized by x-ray diffraction (XRD), x-ray
photoelectron spectroscopy (XPS), x-ray absorption spectroscopy (XAS) and vibrating
sample magnetometry. In the as-deposited films, ferromagnetism was shown to be
caused by the formation of magnetic clusters during the deposition. Heating of
Ti1−xCoxO2−δ
films in a vacuum up to high temperatures and the following quenching thereof result in
partial dissolution of the clusters with the magnetic ions being incorporated into the
matrix. The low-temperature vacuum annealing leads to an increase of weak
ferromagnetism in the semiconductor solid solution.
This work is devoted to the study of the impact of urban development on interethnic intolerance. Although studies on the impact of urbanization and the economic well-being of cities on interethnic intolerance have been conducted in other countries, no similar scientific work has been conducted in Russia. The purpose of this paper is to determine factors related to urban development that influence the level of interethnic intolerance in a Russian city and to clarify the nature of this influence. The assumption of the presence of such an influence is based on the fact that the comfort of the urban environment can play the role of an indicator of economic well-being, while the exacerbation of social conflicts during periods of economic instability is scientifically substantiated. This influence is studied using an econometric study on a sample of 66 Russian cities with a population of over 100 thousand people, where 2 or more crimes motivated by interethnic intolerance were committed during the period 2007–2019. The information base for the study
was obtained from the website of the SOVA Center for Information and Analysis, the statistical databases of Rosstat and EMISS, and the official website of the urban environment quality index. Based on the results obtained, it is concluded that interethnic intolerance is reduced due to a comfortable urban environment. Also, according to the study, in more populated Russian cities the level of interethnic intolerance is higher, whereas the incomes of city residents reduce it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
