Ultrathin magnetic films are used in a variety of technological devices and the ability to manipulate the properties of these films in a predictable way, offers the exciting opportunity to improve existing devices and design new devices. Recent advances in materials science and experimental physics opens the possibility of manipulating materials properties by microscopic structural modification. However the production of prototypes is expensive. This project will use computer simulations and other theoretical methods to study how the magnetic properties of films are modified by such structural modification. The fundamental understanding of this relationship between microscopic structure and macroscopic properties will contribute to our ability to predict how structural modification can be used to generate novel and desirable characteristics of the magnetic film. In the later stages of this work structural modification of other technologically important materials, such as polymers, will also be considered.

超薄磁性薄膜被用于各种技术设备中，以可预测的方式操纵这些薄膜的性能的能力，为改进现有设备和设计新设备提供了令人兴奋的机会。材料科学和实验物理学的最新进展为通过微观结构修饰来操纵材料特性提供了可能性。然而，原型机的生产是昂贵的。本项目将采用计算机模拟等理论方法来研究这种结构修饰如何改变薄膜的磁性能。对微观结构和宏观性质之间关系的基本理解将有助于我们预测如何使用结构修饰来产生新颖和理想的磁膜特性。在这项工作的后期阶段，还将考虑对其他技术上重要的材料（如聚合物）进行结构修改。
