Ferrimagnetic Heusler tunnel junctions with fast spin-transfer torque switching enabled by low magnetization
Chirag Garg, Panagiotis Ch. Filippou, Ikhtiar +10
Magnetic random access memory that uses magnetic tunnel junction memory cells is a high performance, non-volatile memory technology that goes beyond traditional charge-based memori…
Generation of out-of-plane polarized spin current by spin swapping
Binoy K. Hazra, Banabir Pal, Jae-Chun Jeon +9
The generation of spin currents and their application to the manipulation of magnetic states is fundamental to spintronics. Of particular interest are chiral antiferromagnets that…
THz-driven ultrafast spin-lattice scattering in amorphous metallic ferromagnets
S. Bonetti, M. C. Hoffmann, M. -J. Sher +5
We use single-cycle THz fields and the femtosecond magneto-optical Kerr effect to respectively excite and probe the magnetization dynamics in two thin-film ferromagnets with differ…
Experimental Investigation of Temperature-Dependent Gilbert Damping in Permalloy Thin Films
Yuelei Zhao, Qi Song, See-Hun Yang +5
The Gilbert damping of ferromagnetic materials is arguably the most important but least understood phenomenological parameter that dictates real-time magnetization dynamics. Unders…
Facet-dependent giant spin orbit torque in single crystalline antiferromagnetic Ir-Mn / ferromagnetic permalloy bilayers
Weifeng Zhang, Wei Han, See-hun Yang +4
There has been considerable interest in spin-orbit torques for the purpose of manipulating the magnetization of ferromagnetic (FM) films or nano-elements for spintronic technologie…
Spin injection and detection in lanthanum- and niobium-doped SrTiO3 using the Hanle technique
Wei Han, Xin Jiang, Adam Kajdos +3
There has been much interest in the injection and detection of spin polarized carriers in semiconductors for the purposes of developing novel spintronic devices. Here we report the…
Enhanced interface perpendicular magnetic anisotropy in Ta|CoFeB|MgO using nitrogen doped Ta underlayers
Jaivardhan Sinha, Masamitsu Hayashi, Andrew J. Kellock +8
We show that the magnetic characteristics of Ta|CoFeB|MgO magnetic heterostructures are strongly influenced by doping the Ta underlayer with nitrogen. In particular, the saturation…
Negative tunneling magnetoresistance by canted magnetization in MgO/NiO tunnel barriers
Hyunsoo Yang, See-Hun Yang, Dong-Chen Qi +6
The influence of insertion of an ultra-thin NiO layer between the MgO barrier and ferromagnetic electrode in magnetic tunnel junctions has been investigated by measuring the tunnel…
Crossover from Kondo assisted suppression to co-tunneling enhancement of tunneling magnetoresistance via ferromagnetic nanodots in MgO tunnel barriers
Hyunsoo Yang, See-Hun Yang, Stuart Parkin
Recently, it has been shown that magnetic tunnel junctions with thin MgO tunnel barriers exhibit extraordinarily high tunneling magnetoresistance (TMR) values at room temperature1,…
