Planning Grant: International Collaboration on New Ferromagnetic Smart Materials

西密歇根大学的Prina Ari-Gur教授？机械与航空工程系的S将前往芬兰和俄罗斯，计划一个国际合作研究项目，以提高我们对新型Heusler铁磁形状记忆合金的了解。在芬兰，她将拜访赫尔辛基工业大学的Simo-Pekka Hannula教授，他的团队以发展铁磁形状记忆合金和对此类合金结构的基本了解而闻名。在莫斯科，阿里古尔教授将继续访问俄罗斯科学院？在那里，她将与谢尔盖·尼基托夫教授和维克托·科莱多夫教授会面，寻求在单晶生长和制备具有巨大磁热效应的铁磁合金粉末方面的共同兴趣。两部分访问的总体目标是制定一个后续合作计划，该计划将基于西密歇根团队-S在X射线和中子衍射方面的优势，开发对外加磁场具有极高相变敏感度的铁磁性合金。如果长期取得成功，由此产生的新型智能材料应该会在用于低成本永久磁体的金属中显示出相变和形状记忆效应。这一材料研究项目的开发实现了项目目标，即通过使美国和欧洲的专家能够将互补的人才结合在一起，并在共同感兴趣和能力强的领域共享研究资源，从而促进科学知识的发展。更广泛的影响包括加强美国研究界与芬兰和俄罗斯专家在一个领域的联系，在该领域，他们的合作成果可能适用于微观力学和与替代能源相关的问题。

OISE 0831951Ari-GurProfessor Prina Ari-Gur of Western Michigan University?s Department of Mechanical and Aeronautical Engineering will travel to Finland and Russia to plan an international cooperative research project to improve our knowledge of new Heusler ferromagnetic shape memory alloys. In Finland, she will visit Professor Simo-Pekka Hannula at Helsinki University of Technology whose group is known for growing ferromagnetic shape memory alloys and for its fundamental understanding of the structure of such alloys. In Moscow, Prof. Ari-Gur will go on to visit the Russian Academy of Sciences? Institute of Radioengineering and Electronics, where she will meet with Professors Sergey Nikitov and Victor Koledov to pursue mutual interests in growth of single crystals and preparation of ferromagnetic alloy powders that demonstrate giant magneto-caloric effects. The overall goal of the two-part visit is to develop a plan for follow-on collaboration that will build upon the Western Michigan team?s strengths in ex-ray and neutron diffraction to develop ferromagnetic alloys with extremely high sensitivity of the phase transformation to applied magnetic fields. If successful in the long-run, resulting new smart materials should demonstrate phase transition and shape-memory effect in metals for low-cost permanent magnets. This project development in materials research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include stronger links for the U.S. research community with Finnish and Russian experts in a field where results of their cooperation may be applicable to micromechanics and problems associated with alternative energy.
