New cadmium and rare-earth metal molybdates with the formula Cd0.25RE0.50MoO4 (RE=Pr, Nd, Sm-Dy) were synthesized by the solid-state reaction of CdMoO4 with corresponding RE2(MoO4)(3). The obtained compounds crystallize in the scheelite-type structure. They were characterized here by XRD, DTA-TG, IR and EPR methods. The Cd0.25RE0.50MoO4 compounds showed solubility in CdMoO4 forming the CdxRE2-2x(MoO4)(3-2x) (0.50 < x < 1.00) solid solutions. It can be found from EPR measurements of the samples with volatile Gd3+ ions content, that Gd3+ ions can be located at sites of octahedral symmetry, and both temperature and gadolinium content have an influence on local magnetic interaction and relaxation processes of Gd3+ ions.
