摘要：

The ac susceptibility of the amorphous ferromagnetic alloy Fe6Ni74B18Si2 has been measured in different ac and dc fields, at the phase transition from ferromagnetic to paramagnetic. Here we confirm that such measurements are sufficient to extract independently all critical exponents and T-C. Also, the influence of the Earth's magnetic field has been investigated and a method is proposed to take it into account.
