Nanocrystallization and magnetic behaviour of (Fe1-xCox)85.4Zr5.8Me1B6.8Cu1 (x=0 or 0.7; Me=Mo or Nb) alloys

Abstract: We have found that after the annealing of as-quenched ( or Nb) samples at 573K for 1h the decrease of the average hyperfine field due to the invar effect occurs. It is accompanied by the drop of high-magnetic field magnetization. Moreover, the magnetization of as-quenched and annealed at 573K samples of ( or Nb) alloys does not reach the saturation state in the magnetic field up to 1670kA/m. The crystalline -FeCo phase in the nanocrystalline alloy is atomically ordered. The broad maximum in the isochronal disaccommodation curves was observed for the nanocrystalline alloy, in contrary to ( or Nb) alloys. [Copyright &y& Elsevier]
