abstract = {In order to make a new approach to the elucidation of the
microscopic mechanisms of multiferroicity in the RMn2O5
family, experiments with different methods of polarized
neutrons scattering were performed on a TbMn2O5 single
crystal. We employed three different techniques of polarized
neutron diffraction without the analysis after scattering,
the XYZ-polarization analysis, and technique of spherical
neutron polarimetry (SNP). Measurements with SNP were
undertaken both with and without external electric field. A
characteristic difference in the population of 'right' and
'left' helix domains in all magnetically ordered phases of
TbMn2O5, was observed. This difference can be controlled by
an external electric field in the field-cooled mode. The
analysis of the results gives an evidence that antisymmetric
Dzyaloshinsky-Moria exchange is effective in all the
magnetic phases in TbMn2O5.},
