The crystallization kinetics of Fe_(83.3)Si_(4.2)B_(12.5) amorphous alloy in high magnetic fields has been investigated by the DTA and magnetization measurements. In the DTA, the crystallization peak of bcc-Fe(Si) shifts toward a lower temperature side by applying magnetic fields. In the magnetization measurements, the growth curves of bcc-Fe(Si) were obtained by isothermal measurements. The growth curve at 10 T shows the acceleration of crystal growth, compared with that at 0.5 T. These magnetic field effects indicate that the nucleation of bcc-Fe(Si) is enhanced under high magnetic fields.
