The multiferroic phase of DyFeO:an ab--initio study
Alessandro Stroppa, Martijn Marsman, Georg Kresse +1
By performing accurate ab-initio density functional theory calculations, we study the role of electrons in stabilizing the magnetic-field-induced ferroelectric state of DyFeO$…
Hybrid functional study of proper and improper multiferroics
A. Stroppa, S. Picozzi
We present a detailed study of the structural, electronic, magnetic and ferroelectric properties of prototypical \textit{proper} and \textit{improper} multiferroic (MF) systems suc…
Evidence for multiferroicity in TTF-CA organic molecular crystals
Gianluca Giovannetti, Sanjeev Kumar, Alessandro Stroppa +2
We show by means of ab-initio calculations that the organic molecular crystal TTF-CA is multiferroic: it has an instability to develop spontaneously both ferroelectric and magnetic…
Unraveling the Jahn-Teller effect in Mn doped GaN using the Heyd-Scuseria-Ernzerhof hybrid functional
A. Stroppa, G. Kresse
We present an ab-initio study of the Mn substitution for Ga in GaN using the Heyd-Scuseria-Ernzerhof hybrid functional (HSE). Contrary to semi-local functionals, the majority Mn t$…
