中文摘要:
      自旋电子学的某些物理现象,如交换型磁振子、反铁磁共振、超快自旋动力学等,其特征频率刚好处于太赫兹频段。利用相应的自旋电子学现象和原理,研究人员发现和建立了若干新型的太赫兹波产生方法,为新型太赫兹源的实现和发展提供指导方向。这些新型产生方法有:a) 自旋注入产生太赫兹波;b) 基于反铁磁共振的太赫兹波产生;c) 基于超快自旋动力学的太赫兹波产生。理论及实验结果表明,基于自旋电子学的太赫兹产生方法具有较大的潜力,有望推动太赫兹技术的发展。
英文摘要:
      Spintronics is an exciting discipline that involves the study of active control and manipulation of spin degrees of freedom in solid-state systems, the study of spin transport and invention of novel spin-based devices. Some physical phenomena in spintronics, such as exchange magnon, antiferromagnetic resonance, ultrafast spin dynamics, present characteristic frequencies in the THz range. Utilizing the physical principles, the researchers have found and developed several novel THz wave generation methods which give instructions to develop novel THz sources. The methods include: a) THz wave generation based on spin injection; b) THz wave generation based on antiferromagnetic resonance;c) THz wave generation based on ultrafast spin dynamics. THz wave generation methods based on spintronics have great potential which may promote the progress of THz technology.
