The magnetocrystalline anisotropy of Gd--Co phases in the stable region of the Th/sub 2/Zn/sub 17/-type structure changes very sensitively from negative to positive as Gd/Co increases above the stoichiometric ratio. Magnetic properties of single crystals with the compositions of Gd/sub 2/Co/sub 17/ and Gd/sub 2/./sub 1/Co/sub 16/./sub 8/ were measured. K/sub 1/ and K/sub 2/ of Gd/sub 2/Co/sub 17/ at room temperature are -2.7 x 10/sup 6/ and +2.5 x 10/sup 5/ erg/cm/sup 3/, respectively. While, K/sub 1/ and K/sub 2/ of Gd/sub 2/./sub 1/Co/sub 16/./sub 8/ at the same temperature are 3.0 x 10/sup 6/ and 4.7 x 10/sup 5/ erg/cm/sup 3/, respectively. This change of anisotropy is discussed in terms of the crystalline field around Gd and Co sites.
