✦ Synopsis

The HoFeO 3 single crystal was successfully grown by the floating zone technique using a four-mirrorimage-furnace under flowing air. Magnetic properties of HoFeO 3 single crystal were studied over a wide temperature range. Magnetic measurements under different magnetic fields found that the spin reorientation transition in the crystal is well described by the earlier proposed theory with no fitting parameters. Specific heat of HoFeO 3 single crystal was measured from 2 to 300 K under zero magnetic field. Schottky anomaly appeared between 2 and 5 K due to the Ho 3 + spin ordering, and the anomaly of specific heat due to Fe 3 + spin reorientation between 50 and 58 K was observed.
