| 报告介绍 | Abstract:
Tailoring the properties of semiconductor and magnetic structures has been a driving force of information technology. The goal of combining ferromagnetism with semiconductors into a single material has been pursued by physicists and materials scientists for about five decades. A brief review of the history of the magnetic semiconductors will be given before presenting our recent results on HgCr2Se4, a magnetic semiconductor belonging to the spinel group. The revisit to this ¡°old¡± material allowed us to gain new insight into its remarkable electron transport properties such as colossal magnetoresistance. The prospect of a new topological phase emerging from this material will also be discussed. |
