Multiple magneto-ionic regimes in Ta/CoFeB/HfO
R. Pachat, D. Ourdani, J. W. van der Jagt +11
In Ta/CoFeB/HfO2 stacks a gate voltage drives, in a nonvolatile way, the system from an underoxidized state exhibiting in-plane anisotropy (IPA) to an optimum oxidation level resul…

Tuning spin torque nano-oscillator nonlinearity using He+ irradiation
Sheng Jiang, Roman Khymyn, Sunjae Chung +6
We use He irradiation to tune the nonlinearity, , of all-perpendicular spin-torque nano-oscillators (STNOs) using the He fluence-dependent perpendicular magnet…
