We study the possibility of mixed dark matter obtained through the phase space distribution of a single particle. An example is offered in the context of SUSY models with a Peccei-Quinn symmetry. Axinos in the 100 keV range can naturally have both thermal and nonthermal components. The latter one arises from the lightest neutralino decays and derelativizes at [ital z][similar to]10[sup 4].
