Deciphering the origin of spin current in spintronic terahertz emitters and its imprint on their electromagnetic radiation via time-dependent density functional theory
Ali Kefayati, Yafei Ren, M. Benjamin Jungfleisch +3
Spin current flowing between femtosecond laser pulse (fsLP)-driven ferromagnetic metal and adjacent normal metal (NM) hosting strong spin-orbit coupling is invariably invoked to ex…
Charge and spin current pumping by ultrafast demagnetization dynamics
Jalil Varela-Manjarres, Ali Kefayati, M. Benjamin Jungfleisch +2
The surprising discovery of ultrafast demagnetization -- where electric field of femtosecond laser pulse couples to electrons of a ferromagnetic (FM) layer causing its magnetizatio…
Electrical detection of magnon-photon interaction via auxiliary spin wave mode
Peng-Chao Xu, J. W. Rao, Y. Wang +4
We report on the electrical detection of a hybrid magnon-photon system, which is comprised of a magnetic sample coupled to a planar cavity. While the uniform Kittel mode has the la…
Spin and charge pumping in magnetic tunnel junctions with precessing magnetization: A nonequilibrium Green function approach
Son-Hsien Chen, Ching-Ray Chang, John Q. Xiao +1
We study spin and charge currents pumped by precessing magnetization of a single ferromagnetic layer within F|I|N or F|I|F (F-ferromagnet; I-insulator; N-normal-metal) multilayers…
