The project is part of a package proposal aiming at new Fe-Pd based ferromagnetic shape memory alloys for sensor applications. The aim of this project is to identify new FSMA with improved intrinsic properties, i.e. both martensitic and ferromagnetic transition temperatures well above room temperature as well as a high magnetic anisotropy and saturation magnetization. The search will be based on the Fe-Pd system with additions of further elements. The strategy to find new alloys in the Fe-Pd-X(-Y) system will be based on the combinatorial materials science approach, i.e. deposition of thin film materials libraries and high-throughput characterization of these by automated screening technologies. An automated measurement of temperature-dependent magneto-electronic properties for the identification of phase transitions and micro-machined cantilever arrays for the parallel optical detection of the shapememory effect and magnetostrictive effects will be used. The compositional dependencies of martensitic and ferromagnetic phase transformation temperatures, as well as magnetoresistive effects in the Fe-Pd-X(-Y) thin films will be studied in detail in order to optimize film properties. Finally, it will be investigated if field-induced strain can be detected in the newly developed films by using microsystem technology.

该项目是一个一揽子计划的一部分，旨在为传感器应用新的铁钯基铁磁形状记忆合金。该项目的目的是确定具有改进的固有特性的新型FSMA，即马氏体和铁磁转变温度远高于室温以及高磁各向异性和饱和磁化强度。检索将基于Fe-Pd系统，并添加其他元素。在Fe-Pd-X（-Y）系统中寻找新合金的策略将基于组合材料科学方法，即薄膜材料库的沉积和通过自动筛选技术的高通量表征。将使用温度依赖性磁电性能的自动测量来识别相变和微机械悬臂阵列来并行光学检测形状记忆效应和磁致伸缩效应。马氏体和铁磁相变温度的组成依赖性，以及在Fe-Pd-X（-Y）薄膜的磁阻效应将被详细研究，以优化膜的性能。最后，它将被调查，如果场致应变可以检测到在新开发的薄膜，通过使用微系统技术。
