The Premartensite and Martensite in Fe50Rh50 System
Esmaeil Adabifiroozjaei, Fernando Maccari, Lukas Schaefer +19
Metallic/intermetalic materials with BCC structures hold an intrinsic instability due to phonon softening along [110] dirrection, causing BCC to lower-symmetry phases transformatio…
Theoretical current-voltage characteristics of ferroelectric tunnel junctions
H. Kohlstedt, N. A. Pertsev, J. Rodriguez Contreras +1
We present the concept of ferroelectric tunnel junctions (FTJs). These junctions consist of two metal electrodes separated by a nanometer-thick ferroelectric barrier. The current-v…
Polarization states of polydomain epitaxial Pb(Zr1-xTix)O3 thin films and their dielectric properties
V. G. Kukhar, N. A. Pertsev, H. Kohlstedt +1
Ferroelectric and dielectric properties of polydomain (twinned) single-crystal Pb(Zr1-xTix)O3 thin films are described with the aid of a nonlinear thermodynamic theory, which has b…
Exchange parameters in Fe-based molecular magnets
A. V. Postnikov, G. Bihlmayer, S. Bluegel
The calculation of interatomic magnetic exchange interactions entering the Heisenberg model from the standpoint of the density functional theory (DFT) is outlined for two Fe-based…
Electron Spectroscopy and Density-Functional Study of "Ferric Wheel" Molecules
A. V. Postnikov, S. G. Chiuzbaian, M. Neumann +1
The Li-centered "ferric wheel" molecules with six oxo-bridged iron atoms form molecular crystals. We probed their electronic structure by X-ray photoelectron (XPS) and soft X-ray e…
