Quantitative characterization of the spin orbit torque using harmonic Hall voltage measurements
Masamitsu Hayashi, Junyeon Kim, Michihiko Yamanouchi +1
Solid understanding of current induced torques is key to the development of current and voltage controlled magnetization dynamics in ultrathin magnetic heterostructures. To evaluat…
Interface control of the magnetic chirality in TaN|CoFeB|MgO heterosctructures
Jacob Torrejon, Junyeon Kim, Jaivardhan Sinha +4
Recent advances in the understanding of spin orbital effects in ultrathin magnetic heterostructures have opened new paradigms to control magnetic moments electrically. The Dzyalosh…
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…
