Heat-induced damping modification in YIG/Pt hetero-structures
M. B. Jungfleisch, T. An, K. Ando +7
We experimentally demonstrate the manipulation of magnetization relaxation utilizing a temperature difference across the thickness of an yttrium iron garnet/platinum (YIG/Pt) heter…
Terahertz spin currents and inverse spin Hall effect in thin-film heterostructures containing complex magnetic compounds
T. Seifert, U. Martens, S. Günther +20
Terahertz emission spectroscopy of ultrathin multilayers of magnetic and heavy metals has recently attracted much interest. This method not only provides fundamental insights into…
Spin mixing conductance at a well-controlled platinum/yttrium iron garnet interface
Z. Qiu, K. Ando, K. Uchida +6
A platinum (Pt)/yttrium iron garnet (YIG) bilayer system with a well-controlled interface has been developed; spin mixing conductance at the Pt/YIG interface has been studied. Crys…
Time-resolved observation of coherent excitonic nonlinear response with a table-top narrowband THz pulse wave
K. Uchida, H. Hirori, T. Aoki +9
By combining a tilted-pulse-intensity-front scheme using a LiNbO3 crystal and a chirped-pulse-beating method, we generated a narrowband intense terahertz (THz) pulse, which had a m…
Perpendicularly Magnetized Ni / Pt (001) Epitaxial Superlattice
T. Seki, M. Tsujikawa, K. Ito +4
A perpendicularly magnetized ferromagnetic layer is an important building block for recent/future highdensity spintronic memory applications. This paper reports on the fabrication…
Thermal spin pumping and magnon-phonon-mediated spin-Seebeck effect
K. Uchida, T. Ota, H. Adachi +6
The spin-Seebeck effect (SSE) in ferromagnetic metals and insulators has been investigated systematically by means of the inverse spin-Hall effect (ISHE) in paramagnetic metals. Th…
