摘要：

PbEeBO(4) single crystals up to 4 x 2.5 x 0.5 mm(3) in size were grown by spontaneous crystallization from a solution in a melt and their magnetic and dielectric properties were investigated. The high Neel temperature T-N = 114 K and the absence of the broad maximum of susceptibility above the Neel temperature suggest that the PbFeBO4 crystal is a three-dimensional antiferromagnet. The magnetic susceptibility anisotropy in the ordered state indicates that the antiferromagnetic vector is directed along the orthorhombic c axis. The anomalies of dielectric permittivities epsilon' and epsilon '' were observed in both polycrystalline and single crystal samples within the temperature ranges where the short- and long-range magnetic orders are established. This confirms the correlation between the magnetic and electric subsystems in the crystal. (C) 2013 Elsevier B.V. All rights reserved.
