Ivanova N. B. Structure and magnetism of copper substituted cobalt ludwigite Co3O2BO3 [Електронний ресурс] / N. B. Ivanova, N. V. Kazak, Yu. V. Knyazev, D. A. Velikanov, A. D. Vasiliev, L. N. Bezmaternykh, M. S. Platunov // Физика низких температур. - 2013. - Т. 39, Вип. 8. - С. 913-918. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2013_39_8_9 The single crystals Co3O2BO3 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 <$ET sub N> 43 K and high magnetic hardness in this magnetic phase are similar to Co3O2BO3. The small reduction of the effective magnetic moment was revealed under copper substitution.
