Department 02

The Department has a broad range of instrumentation available for the fabrication and analysis of advanced thin-film materials. For the high-quality deposition of nanomaterials and characterization of their properties, we use various equipment listed below.

-    High vacuum chambers for film samples deposition by e-beam evaporation, dc- and rf- magnetron sputtering;
-    Hot isostatic pressing setup for hydrothermal synthesis of nanoparticles;
-    Electrical and magnetoresistance measurements setup;
-    Torque and vibrating sample magnetometers;
-    X-band EPR spectrometer;
-    LEF-3M-1 ellipsometer etc.

At the 9th International Conference on Nanomaterials: Applications & Properties '2019 (Odesa, October, 15-20) the senior research scientist of Department 02 - Physics of Films Dmytro Polishchuk received the Best Presentation and the Best Poster Presentation Awards for the research works in antiferromagnetic spintronics which are carried out in collaboration with Royal Institute of Technology (Stockholm, Sweden).

Joint team of authors from Institute of Magnetism (Kyiv, Ukraine), B. Verkin Institute for Low Temperature Physics and Engineering (Kharkiv, Ukraine) and Royal Institute of Technology (Stockholm, Sweden) reported experimental demonstration of thermoelectric control of magnetic and resistive states in magnetic tunnel junctions (Appl. Phys. Lett. 111, 262401 (2017)). The switching between resistive states was shown in the temperature interval slightly above room temperature, implying its importance for the development of brand-new spin-electronic applications.

Implementation of magnetic nanoparticles in medical technologies encounters substantial difficulties when experimenting with living organisms. Joint efforts of scientists from Institute of Magnetism, Institute of Physics and V.I. Vernadsky Institute of General and Inorganic Chemistry have resulted in the development of the method for realistic modelling of the behavior of ensembles of magnetic nanoparticles in alternating magnetic fields of varied frequencies and amplitudes. The method allows one to minimize a total number of experiments, defines contributions from nanoparticles of different sizes and shows the ways for optimization of their parameters (Phys. Chem. Chem. Phys. 19, 27015 (2017)). The validity of the approach was demonstrated for nanoparticles (La,Sr)MnO3, which are promising heat inductors for magnetic nano-hyperthermia.
