Abstract
PbFeBO4 single crystals up to 4Ã2.5Ã0.5 mm3 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 TN=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 ε' and εⳠwere 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.
