Title: Electronic structure and direct observation of ferrimagnetism in multiferroic hexagonal YbFeO 3

Abstract

Here, the magnetic interactions between rare-earth and Fe ions in hexagonal rare-earth ferrites (h–RFeO 3), may amplify the weak ferromagnetic moment on Fe, making these materials more appealing as multiferroics. To elucidate the interaction strength between the rare-earth and Fe ions as well as the magnetic moment of the rare-earth ions, element-specific magnetic characterization is needed. Using x-ray magnetic circular dichroism, we have studied the ferrimagnetism in h–YbFeO 3 by measuring the magnetization of Fe and Yb separately. The results directly show antialignment of magnetization of Yb and Fe ions in h–YbFeO 3 at low temperature, with an exchange field on Yb of about 17 kOe. The magnetic moment of Yb is about 1.6μ B at low temperature, significantly reduced compared with the 4.5μ B moment of a free Yb 3+. In addition, the saturation magnetization of Fe in h–YbFeO 3 has a sizable enhancement compared with that in h–LuFeO 3. These findings directly demonstrate that ferrimagnetic order exists in h–YbFeO 3; they also account for the enhancement of magnetization and the reduction of coercivity in h–YbFeO 3 compared with those in h–LuFeO 3 at low temperature, suggesting an important role for the rare-earth ions in tuning the multiferroic propertiesmore » of h–RFeO 3.« less
