Influence of Tb on easy magnetization direction and magnetostriction of ferromagnetic Laves phase GdFe2 compounds |
(a) The synchrotron x-ray diffraction patterns (typical 222, 440, and 800 peaks, with wavelength of 0.413677 Å) for GdFe2 at 850 K and 300 K. The resonant black, blue, and red lines are the experimental XRD data and the thinner red and blue lines are the fitted ones. (b) The corresponding cubic and tetragonal structures with lattice parameters. The red arrow shows the easy magnetization direction of the tetragonal phase. |
