Abstract From the measurements of the ac susceptibility of SrRuO3, we determine the critical temperature Tc =159.7±0.2 K and critical exponents δ =2.50±0.15(from the critical isotherm) or δ =3.17±0.20 (from magnetization versus magnetic field at Curie temperature), γ+β = 1.50±0.05 (from the temperature dependence of the internal field of the crossover line), and γ= 0.96±0.05 (from the temperature dependence of the susceptibility along the same line). These exponent values are very close to those predicted by the mean field model.
