摘要：

We have studied the effect of Dy doping on the crystal structure and magnetic properties in hexagonal YMnO3. Dy was substituted at Y site up to x=0.20. Polycrystalline Y1-xDyxMnO3 (x=0, 0.02, 0.05, 0.10, 0.15, and 0.20) were synthesized by solid state reaction method. Room temperature neutron diffraction (ND) provides evidence for no change in crystal structure but lattice parameters gets modify with respect to doping, low temperature magnetization measurements shows modification in Curie-Weiss temperature and Neel temperature. These results are understood in terms of variation in frustration parameter due to Dy induced strain in Y plane of hexagonal YMnO3.
