(Color online) (a) Schematic view of the device and microscope image of the channel region of the device. (b) Setup for TMR measurement. (c) TMR of MTJ-A measured at several temperatures between 50 and .
(Color online) Detection of field-induced DW motion. (a) TMR of MTJ-A and -B at as a function time. corresponds to the time at which is changed from positive value to . (b) Magnetic domain structure monitored by MOKE microscope. The number corresponds to the number in (a) to indicate the time at which the image was taken.
(Color online) Detection of current-induced DW motion. (a) TMR of MTJ-A and -B at , where arrows indicate current pulse sequence. (b) Corresponding MOKE images.
