Abstract

Neutron diffraction measurements performed on a powder as well as on a single crystal compound Ho₃Co reveal complex magnetic structures. The antiferromagnetic ordering sets in at T_N∼22 K followed by a spin reorientation at T₁ ∼ 9 K. In the temperature range T ₁ < T< _N TN the magnetic ordering is associated with the wave vectors k₁ = (0 0 0) and k₂ = (0.1500). Below T₁ higher harmonics of k₂ appear. The 15K k ₁ antiferromagnetic structure corresponds to a 2D and 3D canting of Ho₁ (4c site) and Ho₂ (8d site) magnetic moments, respectively.
