Neutron diffraction study of multiferroic Tb0.85Na0.15MnO3-y

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 (&D*x). This is strongly correlated to the...

Description
Summary: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 (&D*x). This is strongly correlated to the induced oxygen vacancies in Tb0.85Na0.15MnO3-y [y{approximately equal to}0.15(2)].
