Surface Current-carrying Domain Walls
Domain walls, arising from the spontaneous breaking of a discrete symmetry, can be coupled to charge carriers. In much the same way as the Witten model for superconducting cosmic string, an investigation is made here in the case of U(1) × Z2 → U(1), where a bosonic charge carrier is directly coupled to the wall-forming Higgs field. All internal quantities, such as the energy per unit surface an...
متن کاملElectric-field-induced Domain Switching and Domain Texture Relaxations in Bulk Bismuth Ferrite
Bismuth ferrite, BiFeO3, is an important multiferroic material that has attracted remarkable attention for potential applications in functional devices. While thin films of BiFeO3 are attractive for applications in nanoelectronics, bulk polycrystalline BiFeO3 has great potential as a lead-free and/or high-temperature actuator material. However, the actuation mechanisms in bulk BiFeO3 are still ...
متن کاملDisplacement of domain walls under a nanocontact current: Mechanism for magnetoresistance asymmetric switching
We study the action of a magnetic field induced by nanocontact current pulses on the domain walls in thin magnetic films. We show that the pulses of a certain current direction shift the wall to the contact. Such an effect of attraction of the wall to the nanocontact does not depend on the initial position of the wall relative to the contact and results in an increase of nanocontact magnetoresi...
متن کاملGiant effect of uniaxial pressure on magnetic domain populations in multiferroic bismuth ferrite.
Neutron diffraction is used to show that small (∼7 MPa, or 70 bar) uniaxial pressure produces significant changes in the populations of magnetic domains in a single crystal of 2% Nd-doped bismuth ferrite. The magnetic easy plane of the domains converted by the pressure is rotated 60° relative to its original position. These results demonstrate extreme sensitivity of the magnetic properties of m...
متن کاملDirect imaging of current-driven domain walls in ferromagnetic nanostripes
To better understand the response of domain walls to current-induced spin transfer torques, we have directly imaged the internal magnetic structure of domain walls in current-carrying ferromagnetic nanostripes. Domain wall images were acquired both while a constant current was flowing through the wire, and after applying current pulses. Domain walls ranging from vortex walls in wide 1 m wires t...
