Chuanpu Liu,Chuanpu Liu,Jilei Chen,Tao Liu,Florian Heimbach,Haiming Yu,Yang Xiao,Junfeng Hu,Mengchao Liu,Houchen Chang,Tobias Stueckler,Sa Tu,Youguang Zhang,Yan Zhang,Peng Gao,Zhi-Min Liao,Dapeng Yu,Dapeng Yu,Ke Xia,Na Lei,Weisheng Zhao,Mingzhong Wu +21 more
TL;DR: The authors demonstrate the propagation of spin waves with wavelength down to 50 nm and group velocity up to 2600 m s−1 using ferromagnetic nanowires grown on a thin Y3Fe5O12 film strip structure.
Surface-State-Dominated Spin-Charge Current Conversion in Topological-Insulator-Ferromagnetic-Insulator Heterostructures.
Hailong Wang,James Kally,Joon Sue Lee,Tao Liu,Houchen Chang,Danielle Reifsnyder Hickey,K. Andre Mkhoyan,Mingzhong Wu,A. Richardella,Nitin Samarth +9 more
TL;DR: It is shown that the spin-charge conversion efficiency, characterized by the inverse Rashba-Edelstein effect length (λ_{IREE}), increases dramatically as the film thickness is increased from two quintuple layers, saturating above six quint triple layers, suggesting a dominant role of surface states in spin and charge interconversion in topological-insulator-ferromagnet heterostructures.

TL;DR: A spin torque oscillator device driven by pure spin current arising from thermal gradient across an Y3Fe5O12/Pt interface is demonstrated, paving the way towards spin caloritronic devices for microwave and magnonic applications.
Spin–orbit torque-assisted switching in magnetic insulator thin films with perpendicular magnetic anisotropy

TL;DR: The SOT-assisted switching in heavy metal/magnetic insulator systems is reported and can reduce or increase the switching field of the BaFe12O19 film by as much as about 500 Oe when the film is switched with an out-of-plane field.
