| 报告介绍 | 报告摘要：
Low-dimensional magnetic materials have been proposed as building blocks for many intriguing applications, ranging from spintronics to quantum information processing, due to their novel properties which do not present in their bulk counterparts. Many new features of low-dimensional magnetic materials, such as magnetic anisotropy (MA), magneto-optic Kerr effect (MOKE) and quantum anomalous Hall effect (QAHE), are induced by the spin-orbit coupling (SOC). Understanding the role of the SOC in these phenomena is crucial for both fundamental interests and practical applications. In particular, we revealed the underlying physics about the substrate induced spin-reorientation transition (SRT) in Fe-phthalocynine (FePc) molecule. We also demonstrated the feasibility of achieving giant magnetic anisotropy energy (MAE) larger than 60 meV and high structural stability, in systems with transition metal dimers on defected and decorated graphene. For both cases, we found that their magnetic anisotropy can be conveniently manipulated by using external electric field. Furthermore, we proposed a new robust topological state—Chern half metal—in Co deposited graphene. This system is manifested by a trivial metal in majority spin channel but a Chern insulator in minority spin channel. 报告人简介： 胡军，2000年9月－ 2004年7月, 南京理工大学应用物理系，理学学士；2004年9月－ 2009年7月, 中国科学技术大学物理系，理学博士；2009年 8 月－ 2014年7月, 美国加州大学尔湾分校（University of California Irvine）物理系，博士后；2014年8月起，苏州大学物理科学与技术学院，特聘教授。专长于原创性发展和应用能带方法及计算程序，研究复杂材料的物理和化学性能；发展了磁晶各向异性，磁光效应及反常Hall电导率的计算方法。 |
