abstract = "Semiconductor Zn-Mn-O crystallites were synthesized by a solid state reaction method starting from the thermal decomposition of the appropriate oxalates. Samples were thermally treated in air at temperatures ranging from 400 to 900 degrees C. The nominal concentrations of manganese were x = 0.01, 0.02, 0.04 and 0.10. The samples were investigated by the X-ray powder diffraction method, magnetization measurements and by electron paramagnetic resonance. X-ray diffractgrams show a dominant wurtzite structure of Zn-Mn-O. Room temperature ferromagnelism was observed in Zn-Mn-O samples with manganese concentrations x:! 0.04, thermally treated at low temperature (500 degrees C). The saturation magnetization for the sample with x = 0.01 was 0.05 mu(B)/Mn. The room temperature ferromagnetism seems to be due to the diffusion of Zn into the Mn-oxides gains., Ispitivani su poluprovodnički Zn-Mn-O kristali dobijeni metodom sinteze u čvrstom stanju - termičkom dekompozicijom odgovarajućih oksalata i termičkim tretmanom. Termički tretman je izvršen u vazduhu na različitim temperaturama u intervalu od 400 do 900 °C. Nominalne koncentracije mangana su x = 0,01; 0,02; 0,04 i 0,10. Uzorci su ispitivani metodom difrakcije X-zraka na prahu, merenjem magnetizacije i metodom elektronske paramagnetne rezonance. Analiza difraktograma ukazuje na dominantnu vurcitnu kristalnu strukturu sintetisanog Zn-Mn-O materijala. Feromagnetizam na sobnoj temperaturi je uočen na uzorcima Zn-Mn-O sa koncentracijom mangana x ≤ 0,04 termički tretiranim na nižim temperaturama (500 °C). Magnetizacija zasićenja u uzorku x = 0,01 iznosi 0,05 μB/Mn. Ferromagnetna faza je verovatno posledica difuzije Zn u neki manganov oksid.",
