提出了一种基于悬臂梁原理的测量磁性薄膜磁化强度、磁致伸缩和本征应力的新方法。此外，磁各向异性和居里温度的研究也是可能的。可实现的高灵敏度使测量即使在接近单层厚度的薄膜上也能进行。该方法通过本征应力与UHV和char22完全兼容，另外，char22还提供了有关薄膜生长模式和微结构的重要信息。首先，在多晶铁薄膜上的结果令人印象深刻地证明了该技术的性能。
A new method\char22{}based on the cantilever beam principle\char22{}is presented, by means of which quantitative values of the magnetization, magnetostriction, and intrinsic stress of magnetic thin films can be determined. Moreover investigations of magnetic anisotropies and Curie temperature are possible. The high sensitivity achievable enables measurements even on films approaching monolayer thickness. The method is fully compatible with UHV and\char22{}via the intrinsic stress\char22{}additionally provides important information on growth mode and microstructure of the films under investigation. First results on polycrystalline Fe films demonstrate impressively the performance of the technique.
