Hyperfine Field and Atomic Moment of Iron in Ferromagnetic Alloys

Thermodynamic properties of dilute Co-Fe solid solutions studied by 57Fe Mössbauer spectroscopy

“…The values of the parameters of the best-fi t model which were obtained for the spectra are presented in Table 1. These values are in good agreement with corresponding data given in the literature [22,23]. These values were used during the spectral analysis of the annealed samples.…”

On the influence of Joule heating induced nanocrystallization on structural and magnetic properties of Co64Fe21B15 alloy

“…3 shows the dependence of average hyperfine field for crystalline and amorphous phase with Joule heating current. With increase in Joule heating current, the hyperfine field for crystalline phase increases, indicating that the crystalline phase is becoming richer in Fe and the observed values of hyperfine fields for crystalline component (varying between 32 T and 33.5 T) suggest that the hyperfine field of 32 T corresponds to 95% of Co in the crystalline phase and the hyperfine field of 33.5 T corresponds to 80% of Co in the crystalline phase [17]. It should be noted that lattice parameter values show that Co content in the nanocrystals remains constant (80%) with increase in Joule heating current.…”

Hyperfine interactions and electronic band structure in Tb0.27Dy0.73(Fe1−xNix)2 intermetallics

“…Considering dependencies for k ¼ 2, 3 and 4 in Fig. 3a and treating them as functions of the number l, an increase of the magnetic hyperfine field per one Fe/Ni replacement in the second coordination can be estimated as D 2 ¼ 0.33(05) T, 0.41 (20) T and 0.37 (19) T, correspondingly.…”

“…Fe/Ni substitution strongly changes, for instance, the magnetic hyperfine field m 0 H hf (m 0 is the vacuum magnetic permeability) observed at 57 Fe nuclei treated as a function of the average number n of 3d electrons, which varies according to the SlaterePauling curve [17e19] like in 3d metale3d metal alloys [20]. There is experimental evidence that Fe/Ni substitution in RM 2 -type compounds changes the number n of 3d electrons in the M-sublattice, strongly influences the 3d band, and therefore the magnetism, and hyperfine interactions as well.…”
