| Abstract: | Single crystals of cobalt oxyborate Co3BO5 are synthesized. The results of investigations into the structural, magnetic, and electrical properties are reported. It is found that Co3BO5 crystals exhibit two magnetic anomalies at T 1 = 17 K and T 2 = 45 K. The temperature dependence of the electrical resistivity is investigated. Deviations both from the activation law of variation in the electrical resistance and from the Mott variable-range hopping conduction are revealed. |
