AB Tb_xFe_73Ga_27-x (7 at.% ≤ x ≤ 11 at.%) ternary alloys have been obtained by cosputtering from Tb_33Fe_67 and Fe_72Ga_28 targets. In contrast with other Tb-Fe-Ga compounds that consist of just one structural phase, the diffraction pattern of the Tb_7Fe_73Ga_20 shows the presence of two different phases related to binary Tb -Fe and Fe-Ga alloys. This microstructure evolves as the Tb content is increased, and for a Tb of 11 at.% X-ray diffractometry only evidences the presence of a phase close to the TbFe_2. Although none of the studied samples show perpendicular magnetic anisotropy, there is a significant component of the magnetization perpendicular to the sample plane. The increase of the Tb content on the compounds from 7 at.% to 11 at.% enhances this component most probably due to the shift of the microstructure towards one similar to the TbFe_2.
