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.
