The main goal of this work is to study the critical behavior in the annealed LaFe11.0Co0.7Si1.3 alloy in the vicinity of the critical temperature TC. The second order phase transition from the ferro- to paramagnetic state was confirmed by the positive slope of the Arrott plots. Critical exponents (β, γ, and δ) have been revealed using the Kouvel-Fisher method. Moreover, the Kouvel-Fisher analysis revealed the detailed Curie temperatures for all investigated samples.
