Abstract

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 Hcand Hswthan single-layer in nanodots. The investigation on the thickness dependence reveals linear reliance of Hcand Hswon amplification factor. Hcand Hsware further reduced after field annealing at 200 °C. This work provides an approach to reduce the Hcand Hswin nanomagnets.
