Abstract

The T-odd phenomenon of induction of the magnetic field by a static electric field provides to study the electron EDM and constants of T-odd, P-odd interaction of an electron with a nucleus. Measurement of this magnetic field for ferroelectric materials (like PbTiO₃) at the level B~3 10^-18 G allows to derive the electric dipole moment of an electron at the level d_e ~ 10^-30 e cm and the constant of T-odd scalar weak interaction of an electron with a nucleus at the level k₁^nuc10^-9. The atomic magnetometry makes possible to measure fields ~ 10^-13 G/√(Hz) now. This means that for 10 days operation one can expect to obtain B at the level B ~ 10^-16G, and, therefore, the limits for d_e in PbTiO₃ at the level d_e ~ 10^-28 and k₁^nuc~10^-7. that makes the discussed method beneficial for measuring d_e and k₁^nuc.
