摘要: The ac linear (χ 0 ) and nonlinear 2 susceptibilities of a ferromagnetic Ni have been studied near the Curie temperature, to clarify feature magnetic phase transition. first observation for critical behavior χ in pure system has made at low frequency measurement. observed higher frequencies is affected extremely by contribution eddy currents. From analysis dependence , method eddy-current correction found. Analysis yields exponents γ=1.333±0.008 γ =4.69±0.30.
