Effect of Joule heating in current-driven domain wall motion
A. Yamaguchi, H. Tanigawa, T. Ono +4
It was found that high current density needed for the current-driven domain wall motion results in the Joule heating of the sample. The sample temperature, when the current-driven…
Propagation of a magnetic domain wall in magnetic wires with asymmetric notches
A. Himeno, T. Okuno, S. Kasai +4
The propagation of a magnetic domain wall (DW) in a submicron magnetic wire consisting of a magnetic/nonmagnetic/magnetic trilayered structure with asymmetric notches was investiga…
Resistance control of a magnetoresistive manganite by spin-injection
T. Ono, A. Kogusu, S. Morimoto +4
We report a new spin-injection effect found for a manganite using a specially fabricated sample. A wire of La0.7Sr0.3MnO3 was patterned by means of focused ion beam etching, and th…
Real-space observation of current-driven domain wall motion in submicron magnetic wires
Akinobu Yamaguchi, Teruo Ono, Saburo Nasu +3
Spintronic devices, whose operation is based on the motion of a magnetic domain wall (DW), have been proposed recently. If a DW could be driven directly by flowing an electric curr…
