摘要	The structural and magnetic properties of mixed compounds Tb1-xYxFe11Mo with x = 0-1.0 have been investigated by means of x-ray diffraction and magnetic measurements. The compounds crystallize in the tetragonal ThMn12-type structure with space group I4/mmm. The lattice parameters a, c and the unit-cell volume V vary slightly with the Y content, since the atomic radius of Y is close to that of Th. The Curie temperature of the compounds increases for x <= 0. 1, then decreases with the increase in the Y concentration. Spin reorientation phenomena in the Tb1-xYxFe11Mo compounds have been studied in detail. The room temperature easy-magnetization direction of Tb1-xYxFe11Mo compounds changes from planar to the c-axial with increasing Y concentration. Variation of the anisotropy constants of the Fe-sublattice K-1(Fe) (T) with temperature is determined experimentally. By minimizing the magnetocrystalline anisotropy energy, the derived spin reorientation temperature for the Tb1-xYxFe11Mo system shows reasonable agreement with the observations.
