75As spin‐lattice relaxation and resonance in KH2AsO4 type ferroelectric crystals

The temperature dependence of the 75As dipolar spin‐lattice relaxation time in both para‐ and ferroelectric KH2AsO4 and CsH2AsO4 has been determined and the results are related to the microscopic model of the phase transition. The temperature dependences of 75As NQR frequency and linewidth in KD2AsO4 and CsD2AsO4 and the corresponding Rb salts have been as well studied and a good agreement has been found between the theoretical and experimental results.
