Structural and magnetic properties of amorphous and partly crystallized Fe73.5−xCex=0,3,5,7Si13.5B9Nb3Cu1 alloys, were analysed in the temperature ranging from RT to 800 °C with scanning calorimetry and magnetometry. The Fe(Si) and Fe(B) structures were identified and characterised with set of crystallization temperatures and activation energies. Also, Curie temperatures for amorphous and for crystalline...
The determination of percolation threshold is the substantial question for a lot of problems which may be modeled by the formalism of cellular automata. There is a set of well known algorithms which deal with this topic. All of them have some advantages and drawbacks connected to calculational or memory complexity. In our work we are going to present a new approach which we call reducing algorithm...
There is an increasing interest in studying still more complicated magnetic systems. A group of ternary mixed alloys is, among them, a point of interest for as well historical as scientific reasons. The most known material belonging to this group is the famous pigment - Prussian blue. The Prussian blue analogues may be characterized by special properties, like the existence of compensation points...
The progress of technical abilities of computers creates enables the use of still more elaborated computational techniques. The classical examples are here the Monte-Carlo or the Molecular Dynamics simulations which are the sensible alternative to study even quite complicated structures. In this work we want, however, to deal with the problems which may be described as the optimization questions and...
The application of genetic algorithms in a physical problem of modeling of isolated atomic clusters is the topic of our research. Evolutionary algorithms are a mechanism of the global optimization learning about the solution of the search space. This mechanism plays the role of giving the candidates to global optima. We can use the local optimization in the evolutionary process to improve the efficiency...
In the recent years it has been shown that behavior of the human social activities can be successfully simulated by quite simple models. Among them, very interesting due to its discrete representation, seems to be cellular automata. In the presented paper we would like to deal with this approach introducing some corrections to the model of cellular automata with two absorbing states. The simple version...
In the paper we present the short description of physical phenomena related to the motion of ion inside the crystal. The form of this description makes it possible and easy to construct the calculation procedures. The final results are the simulation and experimental data for the Si(001)-Si02-Si(001 (SIMOX) structure. The comparison of the results obtained shows that the problem of energy losses of...
The critical properties of one-dimensional, probabilistic cellular automata with two absorbing states are presented. Size dependent values of critical exponents related to order parameter and its susceptibility is analyzed and some inconsistencies in classification of this model into universality class are discussed.
