Hyperfine interactions in titanates: Study of orbital ordering and local magnetic properties

Hyperfine magnetic fields induced on the nuclei of nonmagnetic ions 139 La and 89 Y in LaTiO 3 and YTiO 3 , respectively, have been microscopically calculated. The dependence of the hyperfine fields on the orbital and magnetic structures of the compounds under study has been analyzed. The comparativ...

Zusammenfassung:Hyperfine magnetic fields induced on the nuclei of nonmagnetic ions 139 La and 89 Y in LaTiO 3 and YTiO 3 , respectively, have been microscopically calculated. The dependence of the hyperfine fields on the orbital and magnetic structures of the compounds under study has been analyzed. The comparative analysis of the calculated and known experimental data confirms the existence of the static orbital structure in lanthanum and yttrium titanates.
