Abstract :
The R2 Fe14-x Six B compounds with R = Pr, Nd, or Er and 
crystallize in the Nd2 Fe14 B tetragonal structure. The Curie temperature increases by ∼ 17 K when one iron atom is substituted by silicon. In the high iron-concentration range the saturation magnetization decreases according to simple dilution behavior. For silicon content higher than 
a rather large variation of the mean iron moments is observed. The anisotropy fields of Pr- and Nd-based compounds are only slightly dependent on composition. A variation of the spin-reorientation temperature in Nd2 Fe14-x Six B and Er2 Fe14-x Six B compounds is shown. The magnetic behavior of the compounds studied is analyzed and correlated with their crystalline structures.
