| Research Abstract |
Dynamics of a single domain wall in artificiaily structured magnetic wires has been investigated.
Summary of this research results is as follows ;
(1)An artificial structure introduced in a magnetic wire can be work as a pinning potential against a domain wall motion.
(2)This pinning potential can work as an ideal single potential barrier against a domain wall motion.
(3)Domain wall velocity as a function of an external magnetic field was determined.
(4)In a magnetic wire with asymmetric structure, the depinning field of a domain wall depends on the direction of domain wall motion.
