Resumen:
It is the aim of the given contribution to present a study of the frequency-dependence of the coercivity in as-quenched (amorphous) and isothermal annealed (nanocrystalline) samples of Mo-doped Finemet alloys. Some data of the magnetic properties of the amorphous magnetic alloys have already been reported at dc [1-2] or low frequency [3] magnetizing field. However, most of commercial applications of these materials are at higher frequencies. Therefore, in this work we present coercivity measurements in the frequency range from 0.5 to 1.3 kHz, in which the frequency-dependence of coercivity is almost linear.
