The magnetic properties and thermal evolution of Tb0.85Na0.15MnO3-y have been studied by neutron-diffraction experiments. By comparison with the TbMnO3 sample, the results show not only small lattice parameters but also a reduction in correlation length (ξ). This is strongly correlated to the induced oxygen vacancies in Tb0.85Na0.15MnO3-y [y≈0.15(2)].
