摘要：

Transport properties of Cd0.96Zn0.04S/Cd0.97Mn0.03S/Cd0.96Zn0.04S multilayer nanowires, deposited in porous anodic aluminum oxide templates by DC electrochemical method, are studied. It is found that the transmission current oscillates against the applied magnetic field, even the thickness of the spin doping barrier is about 96 nm. s-d exchange constant N-0 is obtained from the resonant transmission measurement. A e(-1/T) temperature dependence of N-0 alpha ndicates the electrostatic interaction nature of the s-d exchange interaction.
