The antiferromagnetic ground state has been studied by transverse magnetoresistance, heat capacity and magnetization measurements, which were carried out on high quality single crystals of Tm0.996Yb0.004B12 do-decaboride in strong magnetic fields at liquid helium temperatures. Both antiferromagnetic-paramagnetic (AF-P) and spin-orientation (AF1-AF2) phase transitions have been observed, and allowed to construct a complicated magnetic H-T phase diagram for this compound. Strong magnetoresistance anisotropy was found both in AF states (rho(H parallel to[110])/rho(H parallel to[111]) similar to 1.2 at H similar to 20 kOe) and at the critical field of AF-P transition (H-N[100]/H-N[111] similar to 1.25) in this magnetic metal with a simple fcc crystal structure.
