Popis:	Pseudoternary La2-xCexFe14B compounds having the tetragonal Nd2Fe14B crystal structure have been prepared over the entire 0≤x≤2 composition range. With appropriate heat treatment schedules, samples which were single-phase or nearly so were obtained for x=0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, and 2. Lattice constants (a, c), Curie temperature (TC), and magnetization data are reported for each of these materials. We find that (i) a, c, and TC decrease linearly with Ce content x; (ii) the magnetization at 5 K is essentially independent of x; and (iii) there is no evidence of the occurence of Ce3+ over any range in x.
