Crystal-structure studies on Tm{sub 2}Fe{sub 17{minus}x}Ga{sub x} (x=0, 1, 2, 3, 4, 5, 6, 7, and 8) compounds have shown that the prepared samples are single phase with the 2:17-type structure. Both the unit-cell volume and the saturation magnetization at 1.5 K decrease linearly with increasing Ga content. The Curie temperature is found to increase with increasing x; it goes through a maximum value of 485 K at about x=3 to lower values and then it rises again. The Tm{sub 2}Fe{sub 17{minus}x}Ga{sub x} compounds exhibit a spin{endash}reorientaiton transition at low temperature. X-ray diffraction measurements on magnetically aligned Tm{sub 2}Fe{sub 17{minus}x}Ga{sub x} powders show that the compounds with x{le}6 have the easy-plane type of magnetic anisotropy, whereas the compounds with x{ge}7 exhibit the easy c-axis type of magnetic anisotropy at room temperature. {copyright} {ital 1997 American Institute of Physics.}
