Co$_{3}$Sn$_{2}$S$_{2}$ (CSS) is one of the shandite compounds and becomes a magnetic Weyl semimetal candidate below ferromagnetic phase transition temperature ($\textit{T}_\textrm{C}$). In this paper, we investigate ($\textit{T}$) dependence conversion between charge current spin for CSS thin film by measuring spin-torque resonance (ST-FMR) trilayer consisting / Cu CoFeB. Above $\textit{T}_\textrm{C}$ ~ 170 K, CoFeB exhibits clear ST-FMR signal coming from Hall effect in paramagnetic anisotropic magnetoresistance (AMR) Below $\textit{T}_\textrm{C}$, on other hand, it found that involves dc voltages ($\textit{V}_\textrm{dc}$) not only through AMR but also giant (GMR). Thus, resistance changes both GMR should be taken into account to correctly understand characteristic field angular $\textit{V}_\textrm{dc}$. The torque generated CSS, which possesses same symmetry as effect, dominantly acts magnetization A definite increase spin-charge efficiency ($\xi$) observed at $\textit{T}$ < indicating promotes highly efficient conversion. addition, our theoretical calculation shows conductivity with emergence moment consistent experimental observation.
