Advances in ab-initio theory of Multiferroics. Materials and mechanisms: modelling and understanding
Silvia Picozzi, Alessandro Stroppa
Within the broad class of multiferroics (compounds showing a coexistence of magnetism and ferroelectricity), we focus on the subclass of "improper electronic ferroelectrics", i.e.…

Exceptionally large room-temperature ferroelectric polarization in the novel PbNiO3 multiferroic oxide
X. F. Hao, A. Stroppa, S. Picozzi +2
We present a study based on several advanced First-Principles methods, of the recently synthesized PbNiO3 [J. Am. Chem. Soc 133, 16920 (2011)], a rhombohedral antiferromagnetic ins…

Ab-initio study of the relation between electric polarization and electric field gradients in ferroelectrics
J. N. Gonçalves, A. Stroppa, J. G. Correia +4
The hyperfine interaction between the quadrupole moment of atomic nuclei and the electric field gradient (EFG) provides information on the electronic charge distribution close to a…
