　　北京科技大学长江教授姜勇涉嫌一稿两投被Nature Materials点名

　　Substantial reduction of critical current for magnetization 
switching in an exchange-biased spin valve
　　Y. JIANG, T. NOZAKI, S. ABE, T. OCHIAI, A. HIROHATA, N. TEZUKA AND 
K. INOMATA
　　Nature Materials 3, 361–364 (2004).
　　It has been drawn to the journal’s attention that there is 
considerable overlap between an earlier publication by these authors1 
and the material presented in this paper. At no time during the 
consideration of this paper for publication in Nature Materials did 
the authors inform our editorial staff of the consideration of this 
related work by another journal. The authors’ failure to do so 
constitutes a clear breach of the strict publication policy of Nature 
Materials (http://www.nature.com/nmat/authors/auguide.html).
　　Our readers are reminded that our editorial policy requires that 
all submissions to Nature Materials must be accompanied by copies of 
all related papers that are currently under consideration elsewhere. 
This includes work submitted elsewhere after the original date of
　　submission to Nature Materials. For further discussion of these 
issues, readers are directed to the editorial of the January 2005 
issue of Nature Materials2.

学博士学位。2001.2~2002.8，新加坡国立大学电子工程系信息存储材料实验室
任Research Fellow；2002.8~2004.8日本东北大学工学部任JST研究员。2004.9
回国，现为北京科技大学教授、博士生导师；教育部"长江学者奖励计划"特聘教
授；中南大学兼职教授；中国材料研究会青年委员会理事。研究方向为自旋电子
材料与器件。目前作为负责人承担科研项目10项。2000年以来在国内外A学术期
