Effects of injection current pulses on magnetic domain switching in stable electrodeposited 10nm Ni contacts

Current-Driven Resonances in Magnetic Multilayers

“…[4,30]). We induce spin waves, or ''magnons,'' by means of a high current density ( 10 9 A=cm 2 ) injected into the multilayer film through a point contact between a sharpened Ag tip and the film.…”

Ballistic magnetoresistance in a magnetic nanometer sized contact: An effective gate for spintronics

“…Recently we have developed electrodeposited Ni contacts with diameters in the 10-30 nm range which were stable for days and exhibited BMR of 20% at RT and 500 Oe. 6,7 In addition, BMR can be manipulated by current pulses through the contact. 6,7 The electrodeposited Ni nanocontacts here were grown between two Ni wires of 125 m diameter and 5 mm length ͓see Fig.…”

“…6,7 In addition, BMR can be manipulated by current pulses through the contact. 6,7 The electrodeposited Ni nanocontacts here were grown between two Ni wires of 125 m diameter and 5 mm length ͓see Fig. 1͑a͔͒, similar to the previous work.…”

“…1͑a͔͒, similar to the previous work. 6,7 However, the contacts were grown at the middle of a horizontal wire and a bipotentiostat ͑model AFCBP1, Pine Instrument Company͒ was used in this work to control the potential applied to the two electrodes. Nickel was deposited on the vertical electrode ͓see Fig.…”

Displacement of domain walls under a nanocontact current: Mechanism for magnetoresistance asymmetric switching

“…3͑g͒ coincides with that of the experimental curves. 2,3 The experimental pulse duration Ӎ100 nsӷ5t 0 and so small spikes found in our calculations after the pulses ͓see Fig. 3͑g͔͒ could not be observed in the experiment.…”
