The frequency-domain relaxation response of gallium doped Cd1-xMnxTe

In this paper the complex dielectric permittivity of gallium doped Cd0.99Mn0.01Te mixed crystals is studied at different temperatures. We observe a two-power-law relaxation pattern with m and n, the low- and high-frequency power-law exponents respectively, satisfying the relation m < 1 − n. To interpret the empirical result we propose a correlated-cluster relaxation mechanism. This approach allows us to find origins of both power-law exponents, m and n.
