Giant cobalt-induced anisotropic magnetostriction in GdCo2
An x-ray diffraction analysis of the crystalline structure of the intermetallic compound GdCo2 was performed in the temperature range 5-500 К and giant anisotropic magnetostriction 1X 10~3 was observed at a temperature 5.5 K. From a comparison of x-ray diffraction analyses of the compounds GdAl2, GdNi^ and GdFe2, it is concluded that the anisotropic magnetostriction of GdCo2 is due to the cobalt. The longitudinal and transverse magnetostriction of GdCo2 at Τ = 4.2 К in pulsed magnetic fields up to 230 kOe is also investigated and the large magnetostriction of the paraprocess, caused by the band nature of the magnetism of cobalt in the compound GdCo2, is observed.
