Physics and Applications of Bismuth Ferrite
Gustau Catalan,James F. Scott +1 more
TL;DR: In this paper, the authors summarize both the basic physics and unresolved aspects of BiFeO3 and device applications, which center on spintronics and memory devices that can be addressed both electrically and magnetically.
Journal ArticleDOI

Kalinin,Sibylle Gemming,Feng Wang,Gustau Catalan,James F. Scott,Nicola A. Spaldin,Joseph Orenstein,Joseph Orenstein,Ramamoorthy Ramesh,Ramamoorthy Ramesh +21 more
TL;DR: The observation of room-temperature electronic conductivity at ferroelectric domain walls in the insulating multiferroic BiFeO(3) shows that the conductivity correlates with structurally driven changes in both the electrostatic potential and the local electronic structure, which shows a decrease in the bandgap at the domain wall.
Journal ArticleDOI
Domain wall nanoelectronics
Gustau Catalan,Jan Seidel,Jan Seidel,Jan Seidel,Ramamoorthy Ramesh,Ramamoorthy Ramesh,James F. Scott +6 more
TL;DR: In this paper, a review of magnetoelectric domain walls is presented, focusing on magneto-electrics and multiferroics but making comparisons where possible with magnetic domains and domain walls.
Journal ArticleDOI
Magnetocapacitance without magnetoelectric coupling
TL;DR: The existence of a magnetodielectric (magnetocapacitance) effect is often used as a test for multiferroic behavior in new material systems.
Journal ArticleDOI
Flexoelectric Effect in Solids
TL;DR: Flexoelectricity is a universal effect allowed by symmetry in all materials as discussed by the authors and has been studied in many nanoscale systems, and potential applications of this electromechanical phenomenon have been discussed.
