Powerful and Tunable THz Emitters Based on the Fe/Pt Magnetic Heterostructure
Heterostructures composed of ferromagnetic metal and nonmagnetic metal with strong spin‐orbit coupling are shown to be powerful broadband THz emitters, whose field strength can be maximized by optimizing the thickness of both ferromagnetic and nonmagnetic films, and the heterostructure layers.

| description | Heterostructures composed of ferromagnetic metal and nonmagnetic metal with strong spin‐orbit coupling are shown to be powerful broadband THz emitters, whose field strength can be maximized by optimizing the thickness of both ferromagnetic and nonmagnetic films, and the heterostructure layers. Furthermore, the THz spectrum and its intensity are tunable by the magnetic field orientation applied on the patterned magnetic Fe/Pt heterostructures. |
