- Abstract
- 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. correlated materials
where electronic degrees of freedom (such as spin, charge or orbital) drive ferroelectricity. In particular,
in spin-induced ferroelectrics, there is not only a coexistence of the two intriguing magnetic
and dipolar orders; rather, there is such an intimate link that one drives the other, suggesting a
giant magnetoelectric coupling. Via first-principles approaches based on density functional theory,
we review the microscopic mechanisms at the basis of multiferroicity in several compounds, ranging
from transition metal oxides to organic multiferroics (MFs) to organic-inorganic hybrids. (literal)
