Resumen:
We examine the majorization properties of general thermal-like mixed statesdepending on a set of parameters. Sufficient conditions which ensure the increase in mixedness, and hence of  any associated disorder measure, when these parameters are varied, are identified. We then discuss those exhibiting a power law distribution, showing that they can be characterized by two distinct mixing parameters, oneassociated with temperature and the other with the non-extensivity index  q.Illustrative numerical results are also provided.
