Separating terahertz spin and charge contributions from ultrathin antiferromagnetic heterostructures
Thomas W. J. Metzger, Peter Fischer, Takashi Kikkawa +3
Femtosecond laser excitation of nanometer thin heterostructures comprising a heavy metal and a magnetically ordered material is known to result in the emission of terahertz radiati…
Understanding spin currents from magnon dispersion and polarization: Spin-Seebeck effect and neutron scattering study on Tb3Fe5O12
Y. Kawamoto, T. Kikkawa, M. Kawamata +9
Magnon spin currents in the ferrimagnetic garnet Tb3Fe5O12 with 4f electrons were examined through the spin-Seebeck effect and neutron scattering measurements. The compound shows a…
Detecting bulk carbon ferromagnetism in graphene multi-edge structure
Chao Wang, Nan Jian, Meijie Yin +11
The emergence of bulk carbon ferromagnetism is long-expected over years. At nanoscale, carbon ferromagnetism was detected by analyzing the magnetic edge states via scanning tunneli…
Cryogenic spin Peltier effect detected by a RuO-AlO on-chip microthermometer
Takashi Kikkawa, Haruka Kiguchi, Alexey A. Kaverzin +2
We report electric detection of the spin Peltier effect (SPE) in a bilayer consisting of a Pt film and a YFeO (YIG) single crystal at the cryogenic temperature …
Magnon Polarons in the Spin Seebeck Effect
Takashi Kikkawa, Ka Shen, Benedetta Flebus +5
Sharp structures in magnetic field-dependent spin Seebeck effect (SSE) voltages of Pt/YFeO (YIG) at low temperatures are attributed to the magnon-phonon interact…
Spin current generation from sputtered Y3Fe5O12 films
J. Lustikova, Y. Shiomi, Z. Qiu +4
Spin current injection from sputtered yttrium iron garnet (YIG) films into an adjacent platinum layer has been investigated by means of the spin pumping and the spin Seebeck effect…
