Non-Technical Abstract: Spintronics (or magnetoelectronics) is a multidisciplinary field of research which aims at developing a revolutionary new class of electronic devices exploiting the spin degree of freedom of the electron in addition to the charge. Spintronics is an integral part of nanotechnology whose rapid growth provides a challenge to the academic community to educate students with the necessary knowledge, understanding, and skills. The objective of this Faculty Early Career Development (CAREER) project is to develop a first-rate spintronics research and educational program at the University of Texas at Austin that meets the future demands of nanoscience and nanotechnology. The research agenda of the project is focused on the spin transfer phenomenon which refers to a novel method to manipulate spins using an electrical current. This method offers unprecedented spatial and temporal control of spin distributions and combines interesting fundamental science with the promise of applications in a broad range of technologies. Magnetic microcontact spectroscopy technique will be developed to probe the spin transfer phenomenon on yet unexplored length and time scales. Coherent integration of research and educational activities will expose students of all levels to spintronics and prepare them to conduct research and development of economically feasible and innovative applications.Technical Abstract: Spintronics (or magnetoelectronics) is a multidisciplinary field of research which aims at developing a revolutionary new class of electronic devices exploiting the spin degree of freedom of the electron in addition to the charge.

The research agenda is focused on the spin transfer phenomenon which refers to a novel method to manipulate spins using an electrical current. This method, based on quantum mechanical exchange interaction, offers unprecedented spatial and temporal control of spin distributions with potential applications in a broad range of technologies. Magnetic microcontact spectroscopy will be used to probe the spin transfer phenomenon on yet unexplored length and time scales and search for novel spin transfer effects in antiferromagnetic materials. Coherent integration of research and educational activities will expose students of all levels to spintronics and prepare them to conduct research and development of economically feasible and innovative applications.

非技术摘要：自旋电子学（或磁电子学）是一个多学科的研究领域，其目的是开发一种革命性的新型电子器件，除了电荷之外，还利用电子的自旋自由度。自旋电子学是纳米技术的一个组成部分，其快速发展为学术界提供了一个挑战，以教育学生必要的知识，理解和技能。这个教师早期职业发展（CAREER）项目的目标是在德克萨斯大学奥斯汀分校开发一流的自旋电子学研究和教育计划，以满足纳米科学和纳米技术的未来需求。该项目的研究议程集中在自旋转移现象，这是一种使用电流操纵自旋的新方法。这种方法提供了前所未有的自旋分布的空间和时间控制，并将有趣的基础科学与广泛的技术应用前景相结合。磁微接触光谱技术将被开发来探测自旋转移现象尚未探索的长度和时间尺度。研究和教育活动的连贯整合将使各级学生接触自旋电子学，并为他们进行经济上可行的和创新的应用程序的研究和开发做好准备。技术摘要：自旋电子学（或磁电子学）是一个多学科的研究领域，其目的是开发一个革命性的新一类电子器件，利用自旋自由度的电子，除了电荷。自旋电子学是纳米技术的一个组成部分，其快速发展为学术界提供了一个挑战，以教育学生必要的知识，理解和技能。这个教师早期职业发展（CAREER）项目的目标是在德克萨斯大学奥斯汀分校开发一流的自旋电子学研究和教育计划，以满足纳米科学和纳米技术的未来需求。研究议程的重点是自旋转移现象，这是一种利用电流操纵自旋的新方法。这种基于量子力学交换相互作用的方法提供了前所未有的自旋分布的空间和时间控制，在广泛的技术中具有潜在应用。磁微接触光谱将被用来探测自旋转移现象尚未探索的长度和时间尺度，并寻找新的自旋转移效应在反铁磁材料。研究和教育活动的连贯整合将使各级学生接触自旋电子学，并为他们进行经济可行和创新应用的研究和开发做好准备。
