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…
Magnon spectrum of altermagnets beyond linear spin wave theory: Magnon-magnon interactions via time-dependent matrix product states vs. atomistic spin dynamics
Federico Garcia-Gaitan, Ali Kefayati, John Q. Xiao +1
The energy-momentum dispersion of magnons, as collective low-energy excitations of magnetic material, is computed from an effective quantum spin Hamiltonian but simplified via line…
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…
Cavity mediated manipulation of distant spin currents using cavity-magnon-polariton
Lihui Bai, Michael Harder, Paul Hyde +4
Using electrical detection of a strongly coupled spin-photon system comprised of a microwave cavity mode and two magnetic samples, we demonstrate the long distance manipulation of…
Interfacial Control of Dzyaloshinskii Moriya Interaction in Heavy Metal_Ferromagnetic Metal Thin Film Heterostructures
Xin Ma, Guoqiang Yu, Xiang Li +8
The interfacial Dzyaloshinskii Moriya Interaction (DMI) in ultrathin magnetic thin film heterostructures provides a new approach for controlling spin textures on mesoscopic length…
