Search for: [Abstrakt = "Frequency dependences of imaginary part of the dielectric response ε'\(f\) of SiO2–NaNO2 nanocomposite, prepared by embedding of sodium nitrite into porous glasses with 7 nm average pore diameter, have been studied within a temperature range of 360–520 K. It has been found that the spectrum S\(ω\) = ε'\(f\)\/f contains the component \~1\/fα, where α is a coefficient indicating the dynamical heterogeneity of dipoles. Peculiarities of the temperature dependence of α are discussed."]
