Abstract

The applied-voltage(V) dependence of current(I) passing ferromagnetic Ni quantum wires was investigated with holding a conductance-quantized state. Observed I-V exhibits three-types behaviors: I/V is almost identical up to 50 mV, or increases or decreases with V. The result suggests current-induced reconfiguration of magnetic structures around the quantum wires.
