Abstract

The high quality single crystals of Co2B2O5:Ni were synthesized. The detail study of crystal structure using single-crystal X-ray diffraction was carried out. The monoclinic symmetry was found (P21/c space group). The magnetization and magnetic susceptibility measurements have shown antiferromagnetic behavior below TN = 47 K and paramagnetic temperature = 43 K. The effective magnetic moment per magnetic ion was 3.49 μB, which points out the divalent and high-spin state of Co and Ni ions.
