Optimization of high performance spintronic terahertz sources
Fengwei Guo, Xiaojun Wu, Tianxiao Nie +11
To achieve high efficiency and good performance of spintronic terahertz sources, we propose and corroborate a remnant magnetization method to radiate continuously and stably terahe…
Enhancement of Spintronic Terahertz Emission via Annealing in Ferromagnetic Heterostructures
Xiaojun Wu, Yang Gao, Yanbin He +11
We systematically investigate the influence of annealing effect on terahertz (THz) generation from CoFeB based magnetic nanofilms driven by femtosecond laser pulses. Three times en…
Broadband Magnetic-Manipulated Spintronic Terahertz Emitter with Arbitrarily Tunable Polarizations
Xiaojun Wu, Deyin Kong, Tianxiao Nie +10
Flexible manipulation of terahertz-wave polarization during the generation process is very important for terahertz applications, especially for the next-generation on-chip function…
Femtosecond control of terahertz spin-charge conversion in ferromagnetic heterostructures
Xiaojun Wu, Tianxiao Nie, Bo Wang +11
Employing electron spin instead of charge to develop spintronic devices holds the merits of low-power consumption in information technologies. Meanwhile, the demand for increasing…
