Journal ArticleDOI
Electric relaxation and Mn3+/Mn4+ charge transfer in Fe-doped Bi12MnO20–BiMn2O5 structural self-composite
A. Leonarska,M. Kądziołka-Gaweł,Anna Z. Szeremeta,Renata Bujakiewicz-Korońska,Anna Kalvane,Andrzej Molak +5 more
TL;DR: In this paper, a disorder-related VRH polaron model was proposed for low-temperature relaxations using the electric modulus formalism M″(T) and for electric relaxation processes, which was attributed to the charge transfer between Mn4+/Mn3+ sites.
Journal ArticleDOI
Synthesis and characterization of electrical features of bismuth manganite and bismuth ferrite: effects of doping in cationic and anionic sublattice: Materials for applications
TL;DR: In this paper, the electrical, magnetic, and structural features of bismuth manganite (BM), e.g., BiMnO3, and bistuth ferrite (BF) were reviewed, and the size and morphology of the nanoscale particles were controlled, although they were usually inhomogeneous.
Journal ArticleDOI
Electric Current Relaxation and Resistance Switching in Non-Homogeneous Bismuth Manganite
TL;DR: In this article, the X-ray diffraction pattern analysis of Bismuth manganite ceramics has been carried out and two relaxation processes have been discerned: 1) the cubic I23 phase and 2) the orthorhombic Pbam phase.
Journal ArticleDOI
Electric features of PZT 70/30–BiMnO3 solid solution ceramics
Andrzej Molak,Renata Bujakiewicz-Korońska,Z. Ujma,A. Leonarska,Anna Z. Szeremeta,I. Gruszka,D. M. Nalecz +6 more
TL;DR: In this paper, the density of states was calculated for a 40-atom supercell which corresponds to (Pb 7 Bi)(Zr 4 Ti 3 Mn)O 24 and Pb 7 bi(Zr 3 MnTi 4 )O 24 ceramic compositions.
Journal ArticleDOI
Phenyl Ring: A Steric Hindrance or a Source of Different Hydrogen Bonding Patterns in Self-Organizing Systems?
Andrzej Nowok,Mateusz Dulski,Joanna Grelska,Anna Z. Szeremeta,Karolina Jurkiewicz,Katarzyna Grzybowska,Małgorzata Musiał,Sebastian Pawlus +7 more
TL;DR: In this article, it was shown that the phenyl ring exerts a much stronger effect on the self-organization of molecules via the O-H···O scheme than any other type of steric hindrance, leading to a significant decline in the size and concentration of the H-bonded clusters.
