Аннотация: The single crystals Co ₃O ₂BO ₃ with partial (4%) substitution of Co by Cu ions were synthesized by the flux technique. X-ray diffraction and magnetic properties investigations were carried out. The x-ray diffraction measurements have shown that Cu clearly prefers only one from four nonequivalent crystallographic positions with the smallest electric field gradient. The ferrimagnetic ordering near T _N = 43 K and high magnetic hardness in this magnetic phase are similar to Co ₃O ₂BO ₃. The small reduction of the effective magnetic moment was revealed under copper substitution.
