31.07.2019 – 1.09.2019 During his stay at the Jožef Stefan Institute (Ljubljana, Slovenia) (31.07.2019 – 1.09.2019 and 14.11.2019 – 20.12.2019), S. Ivanchenko worked on the creation of composite polymer-ceramic materials for prototypes of weak magnetic field sensors within the framework of the European Commission project ENGIMA 778072 H2020-MSCA-RISE-2017. Ceramic films with a polymer matrix based on nanopowders (piezoelectric layer 3 μm thick) and CoFe₂O₃ (ferromagnetic layer 2 μm thick) were created by the Tape Casting method. The obtained films were assembled into a multilayer composite by the method of cold isostatic pressing (CIP). SEM studies of the prototypes of multilayer capacitors BaTiO₃+Ni/NiO previously created by S. Ivanchenko confirmed the first case of creating a BaTiO₃ layer with a thickness of <400 nm by the Tape Casting method. Also, S. Ivanchenko studied to work on an atomic force microscope and conducted a study of BaTiO₃ films, which confirmed the surface roughness of Ra 20 nm, with an average particle size of 24 nm, which indicates the high quality of the structure of the formed composites.
