A neutron diffraction and 170Yb Mössbauer investigation of the perovskite ytterbium titanium oxide

A phase with the perovskite structure (Pbnm) and a composition YbTiO2.95 has been prepared by a high-temperature carbothermic method. Neutron diffraction shows a colinear ferrimagnetic structure at 7 K with Yb and Ti moments antiparallel along the c-axis of the orthorhombic cell and an Yb moment of 1.8(3)μB. 170Yb Mössbauer measurements find a more precise and accurate value of 2.0(1)μB from the maximum hyperfine field. From the temperature …
