Application of scanning probe microscopy methods to control the synthesis technology of multilayer structures with Bi-substituted iron garnets

Authors present the synthesis technology in which a lower surface roughness of the layers in multilayer structure with Bi-substituted iron garnets can be achieved through simultaneous crystallization annealing of the bottom Bi-substituted iron garnet layer and the top layer of SiO2.The authors acknowledge support by the RF Ministry of Education and Science (project no.3.7126.2017)

Magnetic force microscopy investigation of domain structure and magnetic recording patterns in high-coercive garnet films with low Curie temperature

Authors present the investigation of domain structures and thermomagnetic recording patterns in iron garnet thin films by magnetic force microscopy. Iron garnet films with low Curie temperature and high coercivity were designed for recording process. Magnetic pattern of PC floppy disc was recorded in iron garnet film by contact printing method. Topography and magnetic structure of floppy disc and iron garnet film before and after thermomagnetic recording process are presented. Accuracy of thermomagnetic recording and parameters, which are influence on it, are discussed.The authors from V.I.

Свойства бутадиен-стирольных латексов, модифицированных кремнийорганическими пав

The properties of butadiene-styrene latexes, stabylized by the mixes of surface-active substances included silicon SAS, practically unsolved in water, were investigated. It was shown that they are characterized by low foaming, practically unswollen in water and stable in the solutions of electrolitesИзучены свойства бутадиен-стирольных латексов, стабилизированных смесями поверхностно-активных веществ (ПАВ), включающих кремнийорганические, нерастворимые в воде. Показано, что они характеризуются низким пено- образованием, практически не набухают в воде, устойчивы в растворах электролитов

Коллоидно-химические свойства ПАВ различной природы на межфазных границах мономер/вода

Colloid-chemical properties of surface active substances of different nature on the boundary of styrene/water, isoprene/water, mixture of styrene and isoprene/water are discussed. It was shown that the mechanism of creation polymer-monomer particles are depending from composition of emulsionВ работе рассмотрены коллоидно-химические свойства эмульгаторов различной природы на границе стирол/вода, изопрен/вода, и смесь стирола с изопреном/вода и показано, что дисперсный состав исходной эмульсии определяет механизм образования ПМЧ
