Dielectric Spectroscopy of Non-Stoichiometric SrMnO₃ Thin Films

Inorganics
The dielectric properties of non-stoichiometric SrMnO3 (SMO) thin films grown by molecular beam epitaxy were systematically investigated. Especially, the effects of cation stoichiometry-induced diverse types and densities of defects on the dielectric ...

Memory function for dielectric relaxation

The Journal of Chemical Physics, 2000
The second-order memory function (SOMF) for the dicyclohexylmetyl-2metyl succinate is obtained by using simple numerical manipulation of the experimental dielectric data. According to the prescription given in a previous paper [J. Chem. Phys. 109, 9057 (1998)], the frequency behavior of the real and imaginary parts of the SOMF is discussed in terms of ...

Relaxation dynamics in multicomponent glass formers with adjustable concentration fluctuations

Journal of Non-Crystalline Solids: X, 2021
Here, we study the structural relaxation kinetics in modified binary (i.e., ternary) mixtures with strong concentration fluctuation imposed by a polar picoline and an apolar triphenylethylene by adding a surfactant phenanthridine.
