The dynamic of the H - bond lenths changes under isotopic substitution is supposed. The mechanisms of the spin - lattice relaxation near the phase transitions temperature in the crystals of the tribromcadmate family crystal was eluminated and it was concluded about type of the ferroelectric phase transition5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
