Mechanism of ferroelectric instabilities in non d^0 perovskites: LaCrO_3 versus CaMnO_3
Mechanism of ferroelectric instabilities non d^0 perovskites
2010/11/24
The incompatibility of partial d occupation on the perovskite B-site with the standard charge
transfer mechanism for ferroelectricity has been a central paradigm in multiferroics research. Nev-erthel...
