| 摘 要： | 通过对电子在量子阱中的运动行为与经典的弦振动的类比，形象地介绍了金属薄膜中磁性交换耦合的量子阱效应机制研究新进展。电子的几率密度变化周期依赖于双量子阱系统的对称性，其振荡周期符合一个晶格调制渡的理论预言双量子阱系统电子波函数的宇称和量子数的变化。

| Abstract: | A brief introduction is given of new studies on quantum well effect to explain the exchange coupling in metal thin films, in which the moving behavior of electrons in quantum wells is analogous to the vibration of a classical string. The periodicity of the spatial variation of the electron wavefunctions depends on the symmetry of the double quantum wells, satisfying a theoretical prediction of the lattice modulated electronic wave. The energy spectrum of the electrons in the double quantum wells depends on the parity of the wavefunctions and the quantum numbers. |
