Abstract

We investigated the current-induced domain wall (DW) motion in Tb/Co multilayered wire with various substrate temperatures (Ts). The coercivity and DW propagation field of the Tb/Co multilayered film are 10 and 8 kOe, respectively. In the Tb/Co wire, the DW velocity is 2.4 m/s for a current density of 4.5 × 1011 Am2 at room temperature. At Ts = 343 K, we also found that the DW velocity is about two times higher than that at room temperature. The enhancement of DW velocity can be attributed to thermally activated creep DW motion and/or the reduction of the depinning current density.
