Using extraordinary Hall resistance ($R_{\text{H}}$) measurements, the material dependence of thermally assisted magnetization reversal (TAMR) was investigated for microstructured multilayers of [Co (0.17 nm)/Pd (0.80 nm)]N with $N = 7$ and 20, which exhibit markedly different magnetic properties. The threshold values of the external field ($H_{\text{w,th}}$) necessary for controlling the magnetization direction in TAMR, obtained by direct application of a current pulse to the sample, were 220 Oe for the $N = 7$ and 710 Oe for $N = 20$ samples. The values of $H_{\text{w,th}}$ are found to be related to the magnetization saturation field at a critical temperature at which apparent coercivity decays.
