Influence of Cr substitution on structural, magnetic and electrical conductivity spectra of LaFeO3
A. Paul Blessington Selvadurai,V. Pazhanivelu,C. Jagadeeshwaran,R. Murugaraj,I. Panneer Muthuselvam,Fangcheng Chou +5 more
TL;DR: In this paper, the authors show irreversibility in the FCC-ZFC curve due to antiferromagnetism and ferromagnetic exchange interaction in LaFeO3.

Band gap tuning and orbital mediated electron–phonon coupling in HoFe1−xCrxO3 (0 ≤ x ≤ 1)
TL;DR: In this paper, the electron-phonon coupling is sensitive to the presence of both the Fe and Cr at the B-site, and the increase in band gap above x 0.5 is attributed to the broadening of the oxygen p-orbitals as a result of the induced spin disorder due to Fe3+ and Cr3+ at B site.

Magnetic properties of YFeO3 nanocrystals obtained by different soft-chemical methods
V.I. Popkov,O.V. Almjasheva,A. S. Semenova,Dina G. Kellerman,V. N. Nevedomskiy,V. V. Gusarov +5 more
TL;DR: In this article, the effect of size and morphological features on magnetic properties of YFeO3 nanocrystals is investigated, and it was shown that synthesized compositions correspond to single-phase nanocrystal of orthorhombic YFe3 with different morphology (isometric, plate-like, rod-shaped) and average crystallite sizes ranging from 29´±´3 to 58´±''6´nm depending on synthesis route.

Superexchange interaction and symmetry properties of electron orbitals
TL;DR: In this article, the sign of the superexchange interaction is closely connected with the symmetry of the electron orbitals and the cation orbital state when the cations are subject to the crystalline field arising from octahedral or tetrahedrally surrounding anions.
