NON-TECHNICAL DESCRIPTION: This university-industry research project pioneers nanoscale magnetometry measurement techniques for advanced energy-related ceramics. The work is predicated by the fact that markedly different magnetic responses will be elicited for ceramics in different materials states, allowing an investigation of nanoscale physical phenomena that have been previously inaccessible. The main scientific objective is to correlate the different magnetic response of ceramic materials with nanoscale-structure features. The results will have broad implication across many technical energy applications where challenges exist in understanding and controlling nanoscale phenomena, but are also expected to impact the ceramics community by helping to advance the metrology of magnetic based measurements. The industrial partner, Quantum Design, is a leader in the magnetic equipment industry and will engage students during the project. The students will also organize and run an annual on-campus conference in ceramics with participation from industry, faculty and members of the local community. TECHNICAL DETAILS: A systematic experimental research program is designed to correlate the magnetic behavior of doped ceramic oxides with nanoscale features that will be independently measured with a suite of materials characterization tools and interpreted with kinetics and thermodynamics theory. The research is based on the fact that the magnetic response of doped ceramics is highly sensitive to different internal material states: (1) the undoped ceramic; (2) metallic ions in solution within the doped ceramic; (3) metallic ions as an oxide; and (4) metal particles. Two host ceramics, one based on ZrO2 and one based on the perovskite structure, are doped with various transition metals (Ni, Co, and Fe) to create a variety of structures that exhibit different magnetic responses. The research lays the foundation to advance the state of nanoscale metrology for magnetometry. Students will be engaged and trained in the potentially transformative magnetometry characterization tools developed.

非技术描述：该大学 - 行业研究项目先驱者纳米级磁力测量测量技术针对先进的能源相关陶瓷。 这项工作是通过以下事实来提出的：不同材料状态中的陶瓷显着不同，从而可以研究以前无法访问的纳米级物理现象。 主要科学目标是将陶瓷材料的不同磁反应与纳米级结构特征相关联。 在理解和控制纳米级现象中存在挑战的许多技术能源应用中，结果将具有广泛的含义，但也有望通过帮助推进基于磁性的测量的计量来影响陶瓷社区。 工业合作伙伴Quantum Design是磁性设备行业的领导者，将在项目期间吸引学生。 这些学生还将组织并举办一年一度的校园内陶瓷会议，并参加了行业，教职员工和当地社区成员的参与。 技术细节：系统的实验研究计划旨在将掺杂陶瓷氧化物的磁性与纳米级特征相关联，该特征将使用一套材料表征工具独立测量，并用动力学和热力学理论来解释。 该研究基于以下事实：掺杂陶瓷的磁反应对不同的内部材料状态高度敏感：（1）未掺杂的陶瓷； （2）掺杂陶瓷溶液中的金属离子； （3）金属离子作为氧化物； （4）金属颗粒。 两种基于ZRO2的宿主陶瓷，一种基于钙钛矿结构的宿主陶瓷，用各种过渡金属（Ni，Co和Fe）掺杂，以创建各种表现出不同磁反应的结构。 该研究奠定了推进纳米级计量学的基础。 学生将受到参与和培训，以开发出潜在的变革性磁力测定表征工具。
