In the article we have found the analytical chiral solutions of stationary Schrödinger boundary problem for domain wall for data storage of nanosize PmBaMn_{2}O_{6} ferroics with incommensurately modulated sinusoidal polarization waves Q_{T}, Q_{P}, Q_{b}. The computer solution of quantized energies or wave vectors of stationary inhomogeneous Schrödinger boundary problem for Q_{T}, Q_{P}, Q_{b} with sinusoidal depolarization waves for the thin PmBaMn_{2}O_{6} nanofilm are specified. We have specified the analytical quantized solutions for the band energy dispersion in nanosize ferroics in framework of Landau-Ginsburg-Devonshire (LGD) theory as well as the numerical computer calculation results for the thin PmBaMn_{2}O_{6} nanofilm have been presented. I think in the article ~\cite{Morozovska2:2010jd} the derived of Phase diagram modeling and domain splitting in thin ferroelectric films with incommensurate phase by A.N. Morozovska et.al. were not allowed and consequently quantized energies or wave vectors were not found by means of the uncertain inference of just these similar symmetrical expressions into \eqref{deqwavevector11&}, \eqref{deq121imag&}.
