| Аннотация |
Defect structures of BaTiO3 nanoparticles annealed in the air and their correlation with magnetic properties have
been studied. As main research techniques, complementary methods such as XPS and positron annihilation
lifetime spectroscopy were used. It was found that low-temperature annealing creates additional oxygen vacancies
in nanoparticles both inside and on the nanoparticle surface, and high-temperature annealing favors the
reduction of Ti. These changes influence nanoparticle magnetism and occur due to the charge compensation
process and grain growth mechanism. Performed studies show that complementary XPS and positron annihilation
spectroscopy are the effective tools to determine nanoparticle surface defect structure, which can be used to
fabricate new rare room-temperature multiferroics materials. |
