摘要
我们在更金色的 Tinkham Klapwijk 模型的框架在量电线 /ferromagnetic-insulator/d 波浪超导体连接(q/FI/d ) 学习了伪粒子运输。我们基于 Bogoliubov-de Gennes 方程在零温度和有限温度作为偏爱电压的功能在 q/FI/d 计算通道传导力。与在 normal-metal/insulator/d 波浪超导体连接的盒子不同，零偏爱的传导力山峰为单个模式的盒子消失。通道传导力系列取决于交换相互作用的大小在铁磁性绝缘体。
We have studied the quasiparticle transport in quantum-wire /ferromagnetic-insulator/d wave super- conductor Junction （q/FI/d） in the framework of the Blonder-Tinkham-Klapwijk model. We calculate the tunneling conductance in q/FI/d as a function of the bias voltage at zero temperature and finite temperature based on Bogoliubov- de Gennes equations. Different from the case in normal-metal/insulator/d wave superconductor Junctions, the zero-bias conductance peaks vanish for the single-mode case. The tunneling conductance spectra depend on the magnitude of the exchange interaction at the ferromagnetic-insulator.
