摘要
The magnetization reversal phenomenon in a submicron magnetic wire with a trilayer structure consisting of NiFe(400 Angstrom)/Cu(200 Angstrom)/NiFe(50 Angstrom) 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.
