Electron doping of the layered nickelate La$_4$Ni$_3$O$_{10}$ by aluminum substitution: A combined experimental and DFT study

Autor: Periyasamy, Manimuthu, Patra, Lokanath, Fjellvåg, Øystein S., Ravindran, Ponniah, Sørby, Magnus H., Kumar, Susmit, Sjåstad, Anja O., Fjellvåg, Helmer

The physical properties of La$_4$Ni$_3$O$_{10}$ with a 2D-like Ruddlesden-Popper-type crystal structure are extraordinarily dependent on temperature and chemical substitution. By introducing Al$^{3+}$ atoms ($x$) randomly at the Ni-sites, the average

Electronic and magnetic structures of hole doped trilayer La(4-x)Sr(x)Ni3O8 from first principles calculations

Autor: Patra, Lokanath, Kishore, M. R. Ashwin, Vidya, R., Sjastad, Anja O., Fjellvag, H., Ravindran, P.

The magnetic and electronic properties of trilayer La4Ni3O8, similar to hole doped cuprates, are investigated by performing full-potential linearized augmented plane wave method-based spin-polarized calculations with LDA and GGA functionals including

Report

Theoretical and Experimental Investigation on Structural, Electronic and Magnetic Properties of layered Mn5O8

Autor: Kishore, M. R. Ashwin, Okamoto, H., Patra, Lokanath, Vidya, R., Sjastad, Anja O., Fjellvag, H., Ravindran, P.

We have investigated the crystal, electronic, and magnetic structure of Mn5O8 by means of state of-the-art density functional theory calculations and neutron powder diffraction (NPD) measurements. This compound stabilizes in the monoclinic structure
