研究方向:凝聚态物理-实验研究
(1)新型磁性拓扑单晶的制备以及磁和输运性质研究
(2)双钙钛矿结构氧化物的合成以及物性研究
(3)新型强关联体系的探索和物性研究
代表性成果:
近几年的研究工作集中在非磁性/磁性量子材料的单晶制备,并基于磁性、电输运、磁电输运和热输运等表征分析材料的物性特征。另外,也对A2B’B’’O6型磁性双钙钛矿材料做了一定研究,主要包括定量控制B-位原子有序度、电子注入提高居里温度、常温下调控晶界强度以优化低场磁阻效应等,这些工作也取得一系列研究成果。迄今,本人以第一作者/通讯作者/共同一作,在Phys. Rev. B,J. Am. Ceram. Soc., J. Phys. D: Appl. Phys.等SCI学术期刊上发表论文30余篇。以第一发明人获授权国家发明专利和实用新型专利共计16项。现列出近年来部分成果,以供各位参考,探寻是否对我的研究方向感兴趣。
