摘要：

Large high-quality single crystals of copper metaborate are grown on the basis of the phase diagram of the ternary Li2O-CuO-B2O3 system. Bright blue crystals with a volume of about 1 cm(3) were grown by the method of spontaneous crystallization while slowly cooling the melt. The magnetic susceptibility and electron spin resonance were measured. It is shown that the effective magnetic moment of a Cu2+ ion is equal to 1.6 mu(B) and the g-factor, to 2.170 and 2.133 for the magnetic field oriented parallel and perpendicular to the fourfold axis, respectively. At 21 and 10 K, sharp anomalies of magnetic susceptibility are observed. (C) 2000 MAIK "Nauka/Interperiodica".
