| Abstract | The stability, crystal structure and magnetic properties of La1-xCexFe13-ySiy have been investigated by x-ray powder diffraction and magnetic measurements. With increasing Ce content x, the solubility y of the Si and the stability of the NaZn13-type structure decrease. The crystal structure of La0.4Ce0.6Fe10.4Si2.6 was refined by the Rietveld method. The refined result indicates that Si atoms preferentially occupy the 96(i) positions in the NaZn13-type structure. The substitution of Ce for La in LaFe10.4Si2.6 results in a compression of the lattice cell volume and a decrease of the Curie temperature and the saturation magnetization. Taking the free ion value for the moment of the Ce3+ (mu(Ce3+) = 2.1 mu(B)), the moment of the Fe atom was derived according to the antiparallel coupling model. The calculated results indicate that the moment of the Fe atom is weakly dependent on the value of x. |
