Аннотация: The magnetic properties of the Nd0.5Gd0.5Fe3(BO3)(4) single crystal have been studied in principal crystallographic directions in magnetic fields to 90 kG in the temperature range 2-300 K; in addition, the heat capacity has been measured in the range 2-300 K. It has been found that, below the N,el temperature T (N) = 32 K down to 2 K, the single crystal exhibits an easy-plane antiferromagnetic structure. A hysteresis has been detected during magnetization of the crystal in the easy plane in fields of 1.0-3.5 kG, and a singularity has been found in the temperature dependence of the magnetic susceptibility in the easy plane at a temperature of 11 K in fields B 1 kG. It has been shown that the singularity is due to appearance of the hysteresis. The origin of the magnetic properties of the crystal near the hysteresis has been discussed.
