| Abstract: | Aharonov-Casher oscillasions of transmission through a mesoscopic ring with a magnetic impurity is investigated.Both spin-dependent transmission and reflection coefficients of spin-state electrons at zero-temperature are calculated as a function of the textured electric fields and its title angle in the present of spin-flipper scattering.It is found that the spin-exchange interaction can destroy intermittently periodic oscillations of spin-up transmission and reflection coefficients within some small ranges in the adiabatic region of quantum phase.However spin-down transmission and reflection coefficients appear periodic AC oscillations.The calculated results manifest that spindown transmission and reflection coefficients have the same perfect oscillation patterns.In the nonadiabatic region, the behavior of the anomalous AC oscillations are depedent on the difference between the tilt angle of spin and that of texture electric field. |
