Numerical modeling and simulation have became and essential part of product development in almost all industries that rely on advanced technology. Nowhere is this more clearly demonstrated than in the data storage industry where computer simulations have played a critical role in the development of new devices and materials that have fuelled the exponential growth in the capacity and speed of magnetic storage that has occurred over the last two decades. The use of numerical modeling allows manufacturers not only to develop new product and reduce costs but also to shorten the product development cycle, essential to maintaining a competitive advantage in industries where success is critically dependant on technological innovation. As the Information Technology industry moves from predominantly stationary terminal devices (desktop pc's etc.) to a wireless enabled, mobile paradigm, the need for innovative, extremely small yet reliable storage will continue to expand.The proposed research will apply and develop numerical simulation techniques to model the behaviour and properties of magnetic multilayers. These materials constitute a key element in the development of future generation data storage media and sensors and the emerging field of spintronics. The proposed research will therefore advance the fundamental science critical to sustaining the rapid pace of development in thin (nano) film technology that has widespread industrial application.  Furthermore, it will also provide the training required to supply the personnel necessary to transfer to industry the knowledge and expertise in materials and device modeling that has been developed through the considerable investment of the Canada Foundation for Innovation (CFI) in high performanace computing (HPC) at Canadian Universities.

在几乎所有依赖先进技术的行业中，数值建模和仿真已经成为产品开发的重要组成部分。没有什么比数据存储行业更清楚地证明了这一点，计算机模拟在新设备和材料的开发中发挥了关键作用，这些设备和材料在过去二十年中推动了磁存储容量和速度的指数增长。数值建模的使用使制造商不仅可以开发新产品并降低成本，而且还可以缩短产品开发周期，这对于在成功关键取决于技术创新的行业中保持竞争优势至关重要。随着信息技术行业从主要的固定终端设备（台式PC等）无线移动的模式，对创新的，非常小的，但可靠的存储的需求将继续扩大。拟议的研究将应用和发展数值模拟技术，以模拟磁性多层膜的行为和属性。这些材料构成了下一代数据存储介质和传感器以及新兴自旋电子学领域发展的关键要素。因此，拟议的研究将推进对维持具有广泛工业应用的薄膜（纳米）技术的快速发展至关重要的基础科学。它还将提供所需的培训，以提供必要的人员，将材料和器件建模方面的知识和专业技术转移到工业界，这些知识和专业技术是通过加拿大基金会的大量投资开发的，创新（CFI）在高性能计算（HPC）在加拿大大学。
