Reduced magnetic coercivity and switching field in conetic-alloy-based synthetic-ferrimagnetic nanodots
The coercivity (Hc) and switching field (Hsw) of free layers increase remarkably with shrinking size, which reduces the sensitivity of spintronic devices. Conetic-alloy-based synthetic ferrimagnetic (SyF) trilayers are proposed to show reduced Hc and Hsw than single-layer in nanodots. The investigation on the thickness dependence reveals linear reliance of Hc and Hsw on amplification factor. Hc and Hsw are further reduced after field annealing at 200 °C. This work provides an approach to reduce the Hc and Hsw in nanomagnets.
