dc.description.abstractU okviru ove doktorske disertacije ispitivan je uticaj parametara mehanohemijske i hemijske sinteze na strukturu i svojstva prahova i keramičkih uzoraka itrijum- -manganita (YMnO3, YMO). Smeša prahova Y2O3 i Mn2O3 mlevena je u planetarnom mlinu tokom vremenskih perioda od 60 – 720 min. Rendgenska analiza dobijenih prahova pokazala je da su tokom mlevenja od 240, 360 i 720 min dobijeni jednofazni pahovi rombičnog YMnO3 (o-YMO). Primarne čestice u prahovima su ispod 100 nm, a produžavanje vremena mlevenja dovodi do aglomeracije. Magnetna svojstva ukazuju da su prahovi u osnovi antiferomagnetični, uz delimično narušeno uređenje spinova prisustvom Mn4+-jona...sr
dc.description.abstractWithin this doctoral dissertation, the influence of mechanochemical and chemical synthesis parameters on the structure and properties of yttrium manganite (YMnO3, YMO) powders and ceramics was investigated. Mixture of Y2O3 and Mn2O3 was milled in a planetary ball mill for periods of 60 – 720 min. X-ray analysis of the resulting powders showed that single-phased orthorhombic YMnO3 (o-YMO) powders were obtained for milling periods of 240, 360 and 720 min. The size of primary particles in the powders was below 100 nm, while a prolongation of the milling time led to agglomeration. The magnetic properties indicated that the powders were basically antiferromagnetic with partially disordered spins by the presence of Mn4+ ions...en
