Structural and magnetic study of Mo-doped FINEMET

In this paper, a study of the structural and the magnetic correlation of the crystalline and amorphous phases in the nanocrystalline system Fe73.5Si13.5B9Nb3−xMoxCu1 (x=0, 1.5, 2, 3) was made. By means of Mössbauer spectroscopy, simple mass balance considerations and density measurements, both phase...

Sumario:In this paper, a study of the structural and the magnetic correlation of the crystalline and amorphous phases in the nanocrystalline system Fe73.5Si13.5B9Nb3−xMoxCu1 (x=0, 1.5, 2, 3) was made. By means of Mössbauer spectroscopy, simple mass balance considerations and density measurements, both phases fractions and chemical compositions were calculated (in at%, wt% and vol%). Then, quasistatic magnetic measurements and ab initio calculations were used in a magnetic balance model in order to estimate the magnetic contribution of the remaining amorphous phase, which was compared to that of as-quenched amorphous samples of the same composition. The difference in both magnitudes showed the influence of penetrating fields and that these became more important for higher crystalline fractions.
