Abstract:
The results of powder neutron diffraction, X-ray resonant and non-resonant scattering in Tb0.95Bi0.05MnO3 demonstrate that substitution of Bi for Tb leads to partial suppression of intrinsic long-range magnetic order in the Tb sub-lattice, which transforms to correlated short-range order. The magnetic order in the Mn sub-lattice remains similar to that of TbMnO3. In the Bi-substituted sample an anomaly in the temperature dependencies of the unit cell parameters was detected at about 100 K.
