Tuning spin torque nano-oscillator nonlinearity using He+ irradiation

Sheng Jiang, Roman Khymyn, Sunjae Chung +6

We use He${}^{+}$ irradiation to tune the nonlinearity, $\mathcal{N}$, of all-perpendicular spin-torque nano-oscillators (STNOs) using the He${}^{+}$ fluence-dependent perpendicular magnet…
