Abstract

Single crystals of Cu2AlBO5 and Cu2GaBO5 copper oxyborates are synthesized via solution-melt crystallization and subjected to X-ray diffraction analysis. Parameters of the crystal lattice and the positions of atoms in a unit cell are determined. Copper ions form a structural chain along axis а in Cu2AlBO5 and Cu2GaBO5. Temperature dependences of the magnetic susceptibility are measured. The obtained curves feature kinks at Т = 2.4 (Cu2AlBO5) and 4.1 K (Cu2GaBO5).
