- Abstract
- The commensurate crystal structure of the magnetic phase occurring below 7 K of the multiferroic
Pb2MnWO6 perovskite has been solved by the introduction of the superspace approach. This lead based
double perovskite is characterized by a complex ferrielectric non-centrosymmetric nuclear structure
with orthorhombic symmetry stable in a wide temperature range. As indicated from the analysis of
powder neutron diffraction data, the low temperature antiferromagnetic structure showing a
propagation vector k 1/4 [1/4 0 0] is stabilized by a multi-step process involving the evolution from
incommensurate to commensurate spin ordering with a concomitant change of the magnetic symmetry.
The determination of the Pb2MnWO6 magnetic structure offers a meaningful example of the superspace
application and provides a detailed phase diagram of the involved magnetic states. Nowadays this
ordered perovskite could be considered as a new type of multiferroic material combining ferrielectric
properties and a long period antiferromagnetic structure. (literal)
