An X-band electron paramagnetic resonance study was made of monocrystals of Cs2M(SO4)2•6H2O, which were doped with Mn2+ ions, at 290 and 77K. It was found that the Mn2+ substituted for divalent cation sites. The spin-Hamiltonian parameters were evaluated. Observations with regard to the temperature dependence of the line-width in the Co salt were explained in terms of spin-lattice relaxation narrowing of the host. Anisotropic and field-dependent line-widths of Mn2+ in the Ni salt were explained in terms of spin quenching.
