Abstract

Investigations of the temperature‐ and concentration dependence of the spin‐lattice relaxation time T~1~ in ferroelectric GASH (= Guanidinium aluminium sulfate hexahydrate) single crystals doped with Cr^3+^‐ions are reported. The concentration‐dependence found on the higher concentrated crystals C 0.1% Cr^3+^) as well as the observed cross‐relaxation are explained in terms of spin‐lattice relaxation via exchange pairs. Using the VAN VLECK formalism T~1~ has been estimated for Cr^3+^: GASH by comparision of the present system and K‐Cr‐alum.
