Temperature evolution of crystal structure of multiferroic Tb0.95Bi0.05MnO3
The temperature evolution of crystal structure of multiferroic Tb0.95Bi0.05MnO3 has been studied by powder neutron diffraction in the temperature range 100—450 K. It is shown that the lattice parameters and volume expansion coefficient demonstrate anomalies in the interval 150—250 K. These anomalies ...
