Opis:: Permittivity in the triglicinium sulphate crystals doped with chromium ions Cr$\text{}^{3+}$ as a function of temperature and of intensity of electric field polarising the crystal was investigated. On the base of thermodynamical theory, the relationship among permittivity, temperature and electric field intensity was calculated. Coefficients of the expansion of the thermodynamic potential were determined. Experimental results were compared with those resulting from the thermodynamical theory.

Opis:: We consider a two-dimensional degenerate electron gas in the presence of perpendicular random magnetic field. The magnetic field disorder which is assumed to be Gaussian is characterized by two parameters. The first is proportional to the amplitude of local magnetic field fluctuations. The second one characterizes the disorder on the longer scale - we call it the screening length. Using the Kubo formula for the conductivity we have found a class of diagrams which leads to the long time tails in the current-current correlation function. For short times in comparison with the diffusion time corresponding to the screening length this function behaves like logarithm of time, for longer times it decays like t$\text{}^{-1}$ which of course brings into question the diffusive character of the behavior of the charged particle in random magnetic field widely assumed in the literature.

Opis:: In a field emission tube with two probe-holes the cross-correlation functions of current fluctuations from potassium submonolayers on tungsten have been investigated. The measurements were carried out in the temperature range of 290-430 K and with coverages between 0.05 and 0.87. The experimental correlation curves were approximated by a sum of three exponential functions revealing three components with different time constants τ$\text{}_{i}$ and amplitudes R. The temperature dependence of the amplitudes R$\text{}_{2}$ and R$\text{}_{3}$ is discussed in terms of collective flip-flop processes.
