基本信息

個人簡介

1998年6月畢業於蘭州大學物理科學與技術學院電子器件與材料工程專業,1998年9月至2003年6月,在蘭州大學物理科學與技術學院攻讀凝聚態物理專業的碩博連讀,研究方向為磁學與磁性材料、穆斯堡爾效應,2003年6月獲得凝聚態物理專業的博士學位。主講普通物理基礎課、實驗課及磁學專業課。先後發表學術論文三十多篇,獲甘肅省科技進步二等獎、甘肅省高校進步一等獎各一次,主持、參加過多項國家自然科學基金、973、863項目的研究工作,入選2007年度教育部新世紀優秀人才支持計畫,2009年被評為蘭州大學巾幗標兵。

研究方向

1. 磁學與磁性納米材料
2. 穆斯堡爾效應在磁性材料中的套用
3. 高頻軟磁材料

研究工作

一直從事磁學與磁性材料的研究工作,特別是對低維磁性材料的巨觀磁性和微觀磁性方面的研究很有特色,曾先後對過渡金屬及其合金、鐵氧體納米線陣列和納米點陣列進行過系統的實驗研究,近年來又開展了低微磁性材料的微磁學模擬。目前正在從事特殊結構磁性薄膜、顆粒及複合材料的低頻、高頻磁性方面的研究工作。
