Highly controllable switching pathways in multiferroic GdMnO
M. Ryzhkov, A. Granero, J. Wettstein +7
Controlling magnetic moments using electric fields remains a central challenge in spintronics. Multiferroics, where magnetic and electric orders coexist, may be a natural platform…
Ferroelectric 180 degree walls are mechanically softer than the domains they separate
Christina Stefani, Louis Ponet, Konstantin Shapovalov +7
Domain walls are functionally different from the domains they separate, but little is known about their mechanical properties. Using scanning probe microscopy, we have measured the…
Unexpected Giant Microwave Conductivity in a Nominally Silent BiFeO3 Domain Wall
Yen-Lin Huang, Lu Zheng, Peng Chen +10
Nanoelectronic devices based on ferroelectric domain walls (DWs), such as memories, transistors, and rectifiers, have been demonstrated in recent years. Practical high-speed electr…
Activation of nominally silent domain wall-localized phonons from GHz to THz frequencies
Peng Chen, Louis Ponet, Keji Lai +2
Ferroelectric domain walls (DWs) are nanoscale topological defects that can be easily tailored to create nanoscale devices. Their excitations, recently discovered to be responsible…
First-principles theory of giant Rashba-like spin-splitting in bulk ferroelectrics
Louis Ponet, Sergey Artyukhin
Recently large Rashba-like spin splitting has been observed in certain bulk ferroelectrics. In contrast with the relativistic Rashba effect, the chiral spin texture and large spin-…
