纳米磁性材料的微波磁谱研究及应用前景
Studies on Microwave Permeability Spectra of Magnetic Nano
-materials and Potential Applications
摘要 纳米材料为凝聚态物理研究的前沿领域,继上世纪七、八十年代,纳米磁性微粒微波物性研究已引起人们广泛关注。十几年前人们又开始对纳米碳管、磁性纳米纤维以及二维磁性纳米膜的微波物性开展了研究,使磁性材料在微波频段的磁导率有了大幅度的提高,这对安全和电磁兼容领域的应用提供了有用的信息。

Abstract Studies on the nano-materials are the front field of the condensed materials
physics.The microwave properties of the magnetic nano-materials have been attracted
much attention since 70-80s of the last century.More than ten years ago,microwave
properties of nano-tubes, magnetic nano-fibers, and two-dimensions magnetic nano
-films are begin to be investigated. The microwave permeability bas been enhanced
significantly. These studies offer the useful information on the applications of magnetic
nano-materials in the fields of security and electromagnetic compatibility.
