Propagation of the magnetic domain wall in submicron magnetic wire investigated by using giant magnetoresistance effect

چکیده
The magnetization reversal phenomenon in a submicron magnetic wire with a trilayer structure consisting of NiFe~400 Å!/Cu~200 Å!/NiFe~50 Å! was investigated by measuring the electric resistance in external magnetic fields. It is shown that the magnetization reversal can be very sensitively investigated by utilizing the giant magnetoresistance effect. The time variation of resistance during the magnetization reversal was also measured and the velocity of the magnetic domain wall propagating in the wire was determined at 77 K. © 1999 American Institute of Physics. @S0021-8979~99!69808-5#

Quantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls
The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...

Magnetization reversal phenomena in a submicron magnetic wire with a trilayer structure were investigated by measuring the electric resistance in external magnetic "elds. The critical "eld for domain wall nucleation was observed to be slightly di!erent for each "eld sweep. The magnetoresistance measurements were repeated 200 times with a sweep rate of 6 Oe/s. The obtained distribution of critic...
متن کاملMagnetoresistance due to domain walls in an epitaxial microfabricated Fe wire
The domain wall ~DW! contribution to magnetoresistance has been investigated using an epitaxial microfabricated bcc ~110! Fe wires of 2 mm linewidth. A strong in-plane uniaxial component to the magnetic anisotropy perpendicular to the wire axis causes a regular stripe domain pattern with closure domains. The stripe domain width in zero-applied magnetic field is strongly affected by the magnetic...

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...
