Magnetotransportna istraživanja manganita La1-xCaxMnO3 (x > 0.5)
2013Oksidi mangana R1−xAxMnO3 (gdje R označava element rijetke zemlje, A alkalijske elemente) predstavljaju jedinstveno područje za istraživanje utjecaja elektronskih korelacija u materijalima koje se odnose na naboj, spin, orbitalne stupnjeve slobode i stupnjeve slobode rešetke budući da su prisutne interakcije usporedive jakosti što ima za posljedicu ...

Utjecaj reaktanata na pripremu manganita reakcijom u čvrstom stanju
2021The purpose of this work was to synthesize compounds of strontium manganite (SrMnO3), lanthanum manganite (LaMnO3), and barium manganite (BaMnO3) by solid-state reaction using two structurally distinct manganese (IV) oxides and therefore examine the influence of reactants on the synthesis. The obtained products were calcined at temperatures of 1000 and

Mecanosíntesis de manganitas de lantano: efecto de la relación en peso bolas: polvo
2011Previous studies of the authors have shown the mechanochemical processing is an effective technique for the synthesis of lanthanum manganites. The novelty of this work is to study the effect of the ball to powder weight ratio, B: P|W, on the process efficiency for this type of manganites.

La1-xCaxMnO3 pripada obitelji manganovih oksida, preciznije manganita, s općenitom kemijskom formulom R1-xAxMnO3, gdje je R element rijetke zemlje, a A alkalni, zemnoalkalni metal ili Pb. Ovi spojevi se istražuju još od 1950., ali postaju posebno interesantni 1994., zbog otkrića kolosalnog magnetootpora (CMR).

Priprava stroncijem dopiranih manganita za višestruku primjenu
Modern society is developing rapidly, with increasing urbanization and industrialization processes, and the quality of life is improving by relying on high energy consumption. According to statistical data, over 80% of the consumed energy is derived from the combustion of fossil fuels, resulting in increased emissions of harmful substances and ...openaire +1 more source
Nelinearna vodljivost tankih filmova manganita La(1-x)Ca(x)MnO(3), x ≥ 0.5
2018Familija manganita kemijske formule La(1-x)Ca(x)MnO3 ima vrlo bogat fazni dijagram u kojem se glavna linija razgraničenja nalazi na koncentraciji x=0.5. Većina istraživanja na ovim sistemima bila je koncentrirana na tzv. poddopirane manganite (x0.5 (predopirani manganiti), je puno manje proučavan.
