摘要
In this paper, a study of the structural and magnetic correlation of the crystalline and amorphous phases in the nanocrystalline system Fe(73.5)Si(13.5)B(9)Nb(3-x)MoxCu1 (x = 0,1.5,2,3) was made. By means of Mossbauer 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. (C) 2010 Elsevier B.V. All rights reserved.
