• Correlating structure with ferromagnetism in melt-spun Gd100−xFex

  X-ray diffraction and transmission electron microscopy measurements of melt-spun Gd100-xFex (0 <= x <= 40) and inert-gas condensed/compacted samples (3.8 <= x <= 12.7) reveal a structure of crystalline hcp-Gd grains surrounded by a non-crystalline Gd1-xeffFexeff. phase, where x(eff) > x is the effective iron concentration within the amorphous region. The two-phase structure is responsible for an unusual dependence of the coercivity on temperature in which non-zero coercivity is observed above the hcp-Gd T-c. with a peak near 320 K. The coercivity decreases as the hcp-Gd grains order, then increases with decreasing temperature. This behavior is explained by the presence of magnetically correlated Fe-rich regions.

• Influence of Zr addition on phase formation and magnetic properties of the Fe17Gd2 phase

  The phase formation in the solid solution range of Zr in Fe17Gd2 phase has been investigated by X-ray diffraction, electron probe microanalysis, and differential scanning calorimetry. Partial substitution of Zr for Gd stabilizes the hexagonal phase Fe-17(Gd,Zr)(2) (space group P6(3)/mmc), which appears in the Fe-Gd binary system as a high temperature phase. Zr atoms show a preference to substitute Gd atoms at the crystallographic (2b) site. The substitution of Gd by Zr leads to an increase in the mean magnetic moment per formula unit up to 15%. The intrinsic magnetic properties of the rhombohedral and hexagonal modification of Fe17Gd2 are comparable. (C) 2003 Elsevier B.V. All rights reserved.
• Critical properties of the paramagnetic-to-ferromagnetic transition in nanocrystalline Gd diluted with Fe

  Nanocrystalline Gd(0.946)Fe(0.054) of average grain size 68 nm was prepared by melt-spinning. The magnetic behavior in the vicinity of the paramagnetic to ferromagnetic transition was investigated via dc magnetization and ac susceptibility measurements. The transition temperature and effective critical exponents for the order parameter and zero-field susceptibility were determined using ArrottNoakes and KouvelFisher analyses. The values obtained were T(C)=291.71+/-0.07 K, beta(eff)=0.385+/-0.009, and gamma(eff)=1.24+/-0.03, respectively. Correction to scaling analysis indicated that the asymptotic exponents were both smaller than the effective ones within the reduced-temperature range investigated, contrary to the behavior seen in monocrystalline Gd. This behavior can be explained in terms of a crossover from 3D short-range Heisenberg universality class to the 3D Ising universality class due to increased anisotropy induced by the high magnetic fields used in the measurements and also possibly due to strain.
