| Abstract: | 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. |
