✦ Synopsis

The sohtonic mechanism for the protonic transfer is used to calculate a mobility of domain walls in hydrogen-bonded ferroelectrics. A one-dimensional model is considered. It is assumed that the sequence of proton jumps in doubleminimum wells of hydrogen bonds brings about a domain wall motion. Calculations carried out for KH>PO, crystals can explain the high mobility of domain walls in these substances.
