Interplay of magnetic and electric coupling across the spin density wave to conical magnetic ordering in a BaHoFeO4 spin-cluster chain compound

In this study, we performed a detailed analysis of the magnetoelectric properties of a polycrystalline BaHoFeO4 system. Rietveld refinement of the synchrotron x-ray powder diffraction pattern (SXRD) with space group Pnma confirmed that the orthorhombic crystal structure was preserved down to the low...

Zusammenfassung:In this study, we performed a detailed analysis of the magnetoelectric properties of a polycrystalline BaHoFeO4 system. Rietveld refinement of the synchrotron x-ray powder diffraction pattern (SXRD) with space group Pnma confirmed that the orthorhombic crystal structure was preserved down to the lowest temperature (T) = 15 K. The DC magnetization indicated complex magnetic behavior with multiple magnetic transitions at TN1 = 49 K, TN2 = 36 K, and TN3 = 7 K. The complex interplay of 3d and 4f magnetic sublattices, and the competing interactions of two different Fe-sites can explain the field (H)-induced metamagnetic behavior in BaHoFeO4 at T
