摘要

通过利用磁性薄膜内存在的交换场，展示了在极低电子能量下对电子自旋方向的操控。片上实验室集成磁隧道晶体管的设计可以测试不同的磁性材料。结果表明，薄膜厚度、交换场强度或电子能量的变化会影响电子穿过铁磁材料时的自旋方向。因此，磁性薄膜中交换场的可控工程可作为未来可控自旋操纵设备的基础。

Low-Energy Spin Manipulation Using Ferromagnetism

The manipulation of the electron spin direction at very low electron energies is demonstrated by exploiting the exchange field present within a magnetic thin film. The design of the lab-on-chip integrated magnetic tunnel transistor allows to test different magnetic materials. The variation of film thickness, exchange field strength or electron energy are shown to have an impact on the resulting spin direction of electrons crossing a ferromagnetic material. A controlled engineering of the exchange field in thin magnetic films can therefore serve as a basis of future devices enabling controlled spin manipulation.

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
