摘要：

Structural and magnetic properties of polycrystalline Yb1-xMgxMnO3 (x = 0, 0.05 and 0.10) hexagonal compounds prepared by solid state method, have been studied. The structural analyses of the samples were carried out by Rietveld analysis of neutron diffraction data. With increasing Mg content, we find that the lattice parameter a decreases and c increases whereas the overall Mn-O bond length decreases. Magnetization measured as a function of magnetic field at 2.5 K exhibits hysteresis, which is attributed to ferromagnetic like ordering of Yb3+ sublattice. Temperature dependence of ac magnetic susceptibility, chi(ac)(T), shows no signature of spin-glass behavior. chi ''(T) exhibits a sudden increase at low temperatures which is due to ordering of Yb3+ sublattice.
