Abstract
Subject headings
Close
- We report on the magnetodynamic properties and the magnetization auto-oscillations of ultra-low current 20 nm width nano-constriction spin Hall nano-oscillators (SHNOs) fabricated on different substrates and seed layers. Combining an optimized W88Ta12 alloy, low damping CoFeB, and a moderate perpendicular magnetic anisotropy, we push the threshold current down to 35 μA in the best devices. The best overall magnetodynamic properties and lowest threshold currents are obtained when using a 3 nm thick AlOx seed layer in between the high-resistance Si substrate and the W88Ta12 layer.
