Abstract
The TbMn6Ge6-xGax (0.05≤x≤0.60) and TmMn6Ge6-xGax (0.2≤x≤1.0) compounds have been studied by magnetization measurements in the temperature range 10-600 K. The TbMn6Ge6-xGax compounds order ferrimagnetically above room temperature (452≥Tc≥438 K). The low Ga content compounds (x≤0.2) display a ferri- to antiferromagnetic transition on cooling (363≥T1≥181 K) and a second Curie point at lower temperature (49≤Ty≤108 K). The high Ga content compounds display ferrimagnetic ordering in their whole ordered range and a spin reorientation transition at low temperature (112≤TSF≤162 K). The TmMn6Ge6-xGax compounds (x≤0.8) order antiferromagnetically above the room temperature (476≥TN≥372 K) and except TmMn6Ge5-8Ga0.2, display a ferrimagnetic ordering at lower temperature (32≤Tc≤250 K). TmMn6GF5Ga is ferrimagnetic in its whole ordered range. The Ga-rich compounds (x≥0.6) display a spin reorientation process around 50 K. All the ferrimagnetic compounds display large anisotropy effects at low temperature. The coercive fields measured for TbMn6Ge5.4Ga0.6 and TmMn6Ge5Ga1 are greater than 25 and 20 kOe, respectively. The evolutions of the magnetic properties and magnetocrystalline anisotropy are discussed.

(0.2≤x≤1.0) compounds have been studied by magnetization measurements in the temperature range 10-600 K. The TbMn<sub>6</sub>

compounds order ferrimagnetically above room temperature (452≥T<sub>c</sub>
≥438 K). The low Ga content compounds (x≤0.2) display a ferri- to antiferromagnetic transition on cooling (363≥T<sub>1</sub>
≥181 K) and a second Curie point at lower temperature (49≤T<sub>y</sub>
≤108 K). The high Ga content compounds display ferrimagnetic ordering in their whole ordered range and a spin reorientation transition at low temperature (112≤T<sub>SF</sub>
≤162 K). The TmMn<sub>6</sub>

Ga is ferrimagnetic in its whole ordered range. The Ga-rich compounds (x≥0.6) display a spin reorientation process around 50 K. All the ferrimagnetic compounds display large anisotropy effects at low temperature. The coercive fields measured for TbMn<sub>6</sub>
