Dependence of band gaps in d-electron perovskite oxides on magnetism
Julien Varignon, Oleksandr I. Malyi, Alex Zunger
Understanding the controlling principles of band gaps trends in d electron perovskites is needed both for gauging metal-insulator transitions, as well as their application in catal…
Hybridization-controlled charge transfer and induced magnetism at correlated oxide interfaces
M. N. Grisolia, J. Varignon, G. Sanchez-Santolino +11
At interfaces between conventional materials, band bending and alignment are classically controlled by differences in electrochemical potential. Applying this concept to oxides in…
Analysis of the multiferroicity in the hexagonal manganite YMnO3
Kiran Singh, Marie-Bernadette Lepetit, Charles Simon +4
We performed magnetic and ferroelectric measurements, associated with Landau theory and symmetry analysis, in order to clarify the situation of the YMnO3 system, a classical exampl…
Role of the ferromagnetic component in the ferroelectricity of YMnO3
Kiran Singh, Natalia Bellido, Charles Simon +4
We performed magnetic and ferroelectric measurements, first principle calculations and Landau theory analysis on hexagonal YMnO3. The polarization and the AFM order parameter were…
