摘要: Abstract We have found that the Curie temperature (Tc) of Co-based amorphous alloy Co90Nb10Ta3 (Tc = 360 K) is much lower than many systems. Through further research, we exists second-order ferromagnetic (FM) to paramagnetic (PM) phase transition near Tc. Tc has a larger magnetocaloric effect (MCE), under ΔH = 60 kOe, - Δ S M max =2.43 J kg−1K−1, relative cooling power (RCP) can reach 203.55 J/kg. Compared with Fe-B-Cr, Fe-Cr-Cu-Nb-Si-B, FeCoSiAlGaPCB and FeCrMoCuGaPCB alloy, Co-Nb-Ta better properties. mechanical chemical properties other alloys, it potential MCE material.
